%%  This file is asmeconf-template.tex, a LaTeX template to format ASME Conference papers according to
%%  the requirements on ASME's conference web pages, and including hypertext support for the pdf.
%%
%%  This file is version 1.41 dated 2025/03/27
%%  
%%  As of version 1.11, this template defaults to ASME's newer conference guidelines first posted July 2019.
%% 			Those guidelines changed the author block formatting to be inline. 
%%			If you need the traditional grid format, use the class option [grid].
%%			Nomenclature now follows the abstract, and abstract text is set in italics.

%%
%%  Class options include:
%%
%%          * An option to use the traditional grid arrangement of author names, [grid].  
%%			*	 With this option, line breaks (\\) may be inserted into the address as needed. 
%%			*	 Author names that include commas should be enclosed in braces, e.g., {Joseph L. Smith, Jr.}.  
%%			*	 Authors may be grouped above a single affiliation using braces, e.g., {Henry Tudor, Catherine Parr}.
%%
%%          * An option to balance the heights of columns on the last page [balance]. 
%%
%%          * An option to include line numbers, [lineno]. You must *run twice* for proper placement of the line numbers. 
%%			*	 The lineno package does not number titles, footnotes, captions, or tables.
%%          *    This option will disable balancing column height on final page if that option has been invoked.
%%          *    The lineno package won't always number the lines preceding displayed math in a paragraph because
%%          *    paragraph has not ended.  See that package's documentation for macros to address this problem, or
%%          *    just leave a blank line above the displayed equation while you are editing and then remove the 
%%          *    blank line with [lineno] option when you move to your final version.
%%
%%			* An option not to use a boldface font for caption text, [unboldcaption]
%%
%%          * Options to: 	omit the ASME copyright footer, [nofoot]; 
%%			*				use government employee copyright notice, [govt];
%%			*				use government contractor copyright notice, [contractor];
%%			*				use copyright notice for some gov't employees, [somegovt];
%%			*				omit the conference headers on the titlepage, [nohead]
%%
%%			* Option to use LuaLaTeX **without** unicode-math and fontspec, [nofontspec]
%%
%%          * Math options from M. Sharpe's newtxmath package: upright integrals [upint]; 
%%          *    [varvw] for a v and w that are better distinguished from Greek nu; and also 
%%          *    [subscriptcorrection, smallerops, varg, frenchmath, varbb, cmbraces, slantedGreek,...] 
%%			* 	 See newtx documentation for descriptions (at CTAN: https://www.ctan.org/pkg/newtx, v1.6 or higher is best).
%%			*	 newtx is not loaded with lualatex unless the [nofontspec] option is used.
%%
%%          * An option to allow hyphenation of the typewriter font [hyphenate], from the inconsolata package.
%%          *    Hyphenation is normally suppressed for typewriter mode because it is often used for code.
%%			*	 To replace the default variable word spacing by monospacing, use the option [mono].
%%			*	 To get a zero without a slash, use [var0]
%%
%%			* PDF/A compliance:  Since 2022, LaTeX has included integrated support for pdf-a, through the \DocumentMetadata{..}
%%			*    command. This approach works with both pdfTeX and LuaLaTeX.
%%
%%          * Options (used by the babel package) to include passages in languages other than English (e.g., a translation 
%%			*    of the abstract). Languages may be called as options, e.g. [spanish], [greek], [russian], etc., but 
%%			*    see Appendix C for details. 
%%			*    Language support is most extensive when running LuaLaTeX, which automatically loads fontspec, but
%%			*	 be aware that you might to install additional fonts on your system for some languages.
%%			 
%%  The use of commands defined or modified by the asmeconf class is illustrated throughout this file. In particular, 
%%  ASME requires capitalized section headings, and as a result some care is needed when using macros in section headings,
%%  as also illustrated below.
%%
%%  Be sure to use **up-to-date and complete** installation of LaTeX, such as TeX Live 2023 or later. Errors often occur with old set-ups.

\begin{abstract}
This paper is an example of and a {\upshape\LaTeX} template for typesetting ASME conference papers using the {\upshape\texttt{asmeconf}} class. This  {\upshape\LaTeX} template follows ASME guidelines for margins, fonts, headings, captions, and reference formats as of 2025. The class should be used with the {\upshape\texttt{asmeconf.bst} \hologo{BibTeX}} style for reference formatting, which is part of this distribution. The template produces pdfs that contain hyperlinks, bookmarks, and metadata; and references can include the DOI and URL fields. Links may be colored, for online use, or black, for publication. The class enables inline author names, following ASME's current style, but can also produce the traditional grid style. Options include line numbering, final column balancing, various math options, government copyright, and archivability (PDF/A). In addition, section headers may contain mathematics, references, citations, and footnotes. The class is compatible with {\upshape\hologo{pdfLaTeX}} or {\upshape\hologo{LuaLaTeX}}.

%%%%%%%%%  BODY OF PAPER %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\section{Introduction}
The \texttt{\hrefurl{https://ctan.org/pkg/asmeconf}{asmeconf}} class typesets papers with margins, fonts, headings, captions, and reference formats that follow the specifications for conference papers of the American Society of Mechanical Engineers (ASME). The \texttt{asmeconf} class will set internal and external hyperlinks, and the pdf file will contain bookmarks and metadata. Many other useful features have been incorporated. This class is not a publication of ASME, but the author has published in ASME conferences since 1983. 

The \texttt{.tex} file may be written using standard \LaTeX\ commands, although some class-specific initial commands are needed to format the blocks containing the author[s], title, and abstract.  This class loads a number of other packages, all of which are contained in up-to-date versions of \hrefurl{https://www.tug.org/texlive/}{\TeX\ Live}, \hrefurl{http://www.tug.org/mactex/}{Mac\TeX}, and similar platforms. If you get an error message about a missing package, you can download that package at no cost from CTAN (\hrefurl{https://ctan.org}{ctan.org}). 

\subsection{Essential Initial Commands}

To begin, fill in the fields to be completed at top of the \texttt{asmeconf-template.tex} file. These fields include the headers for your conference and your paper number. The metadata you provide will be placed into the pdf file itself. 
The title should be placed into \verb|\title{..}|. 

Put author names into the \verb|\SetAuthors{name, name,...}| command in the desired order; follow the syntax illustrated \texttt{asmeconf-template.tex} file. Put each distinct address sequentially into a separate \verb|\SetAffiliation{n}{address}|, where $n = 1,2,\ldots$ Tag each author with an affiliation by putting \verb|\affil{n}| after that author's name inside the \verb|\SetAuthors{..| command. 

Keep author addresses short.  List the author institution, and the City, State (US authors), City, Province, Canada (Canadian authors), or City, Country (other international authors). 

One author (or more) may be designated as the corresponding author by placing \verb|\CorrespondingAuthor{email}|  after \verb|\affil{n}|. Two or more authors may be joint first authors by putting \verb|\JointFirstAuthor| after \verb|\affil{n}|.

After setting up the headers, authors,  and title, issue the \verb|\maketitle| command. 

The abstract text must be placed into \verb|\begin{abstract}| \ldots \verb|\end{abstract}|. The abstract will automatically be italicized. Keywords may be included using the \verb|\keywords{..}| command. The \texttt{keyword} command \textit{must} be issued before the abstract environment. 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\section{Referring to Citations, Figures, and Equations}

Citations are automatically numbered \cite{ning2002}. They should be inserted in the text using a \verb|\cite{ref}| command~\cite{gibson2008,stevens1999}. The citations will be automatically sorted and compressed if they are given in a set \cite{stevens1999,ning2002,gibson2008,wions2005,smith2002,watson1982}. 
A specific reference may be named with an abbreviation, as in Ref.~\cite{watson1982}.
See the \texttt{asmeconf-sample.bib} file and Sect.~\ref{sec:references} for examples of entering references.

For ASME conference papers, the labels Equation and Figure should be abbreviated when they do not start a sentence, as in  Eq.~\eqref{eqn:dw} and Fig.~\ref{fig:1}. Figure~\ref{fig:1} is spelled out when it starts a sentence. Equation~\eqref{eqn:dw} is spelled out when it starts a sentence. 

Equations are typeset in the usual way and will be automatically numbered.  The class file loads the \texttt{amsmath} and \texttt{mathtools} packages. Further, the \texttt{newtxmath} package used for the math fonts includes many additional math features (see Sect.~\ref{sec:moremath}).
\begin{equation}\label{eqn:fourier}
\vec{q} = -k\nabla T
\end{equation}

ASME prefers SI units. (U.S.\ style units may follow in parentheses.) Be sure to put all symbols into the nomenclature list, including their units.

\end{figure}
 
%%%%%%%%%%%%% end figure %%%%%%%%%%%%%%%%%%%


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%% Use title case for subsections and subsubsections (first letter of words capitalized)

\section{Section Headings and Captions}

ASME requires that section headings and captions be set in an uppercase, sans serif font.  The class will do this automatically.  You can place \verb|\cite{..}|, \verb|\ref{..}|, \verb|\label{..}|, and mathematics into headings and captions directly, as you would in the main text. Do not enclose them braces, e.g.\ \verb|{\cite{..}}|, which will cause errors. You can place \verb|\footnote{..}| into headings, but not into captions.\footnote{See \texttt{tex-stackexchange} for various approaches to footnotes in captions, if they seem necessary. For footnotes in tables, use the \texttt{tablefootnote} package.}\footnote{Sequential footnotes are automatically separated by a comma.}

Text in section headings and captions will not be capitalized if enclosed in a \verb|\NoCaseChange{..}| command.

Sections may either be numbered or left unnumbered.

Simple mathematical expressions can be used in either captions or section headings. For a section heading that includes more complicated math (and macros), you may use the optional argument of \verb|\section[..]{..}| to create a pdf bookmark without losing characters or producing warnings or errors. See the \texttt{asmeconf-template.tex} source file for examples of this procedure. These bookmarks should usually be text expressions, although some math is supported.  

To eliminate boldface type in caption text and math, use the class option \texttt{[unboldcaption]}.  To prevent sans-serif math, put \verb|\NoCaseChange{\mathversion{normal}}| in the caption.

\subsection{Subsection and Sub-subsection Headings}

Subsections and sub-subsection headings should be entered in title case, with the first letter of primary words capitalized. Sub-subsections (i.e., paragraphs) are never numbered.

\section{Tables and Figures}

Table \ref{tab:1} is an example of a simple table. Table captions should be placed above tables.
The class loads the \texttt{booktabs} package (used for horizontal rules in Tables \ref{tab:1} and \ref{tab:2}), and the \texttt{array} and \texttt{dcolumn} packages which provide extended capabilities for columns in the \texttt{tabular} environment (see Table \ref{tab:2}).  Table \ref{tab:3} is an example of a table that spans two columns. Two column tables (and figures) will always float to the top of a later page.

Figure captions go below figures. Figure~\ref{fig:2} is an example of a figure that spans two columns and includes subfigures. The text in figures (and tables) should be no smaller than 6~point type. Images in figures are handled by the standard \texttt{graphicx} package.

Landscape figures and tables may be produced at full-page size by putting \verb|\usepackage[figuresright]{rotating}| in your \texttt{.tex} file's preamble and using the \texttt{sidewaystable*} and \texttt{sidewaysfigure*} environments~\cite{fairbairns}.


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\section{Reference Formatting with \NoCaseChange{\texttt{asmeconf.bst}}\footnote{To prevent capitalization of text in a section heading or caption, such as an SI unit, enclose it in a \texttt{\textbackslash NoCaseChange} command. As of the July 2022 release of \LaTeX, commands used in a heading or caption may be protected globally by putting this in the preamble: \texttt{\textbackslash AddToNoCaseChangeList\{\textbackslash MyCommand\}}.}}\label{sec:references}

The {\upshape\texttt{asmeconf.bst}} \hologo{BibTeX}  style follows the reference styles shown on ASME's conference web site in  2025.\footnote{\texttt{asmeconf.bst} is intended as a replacement for the old \texttt{asmems4.bst}, which does not follow ASME's current reference formats or support DOI and URL.}
Examples for these and many other cases are given in the \texttt{asmeconf-sample.bib} file, which is part of this distribution. Citations and references are managed by the standard \texttt{natbib} package.  Nevertheless, a few comments are necessary. 

%% sub-subsections should *not* be numbered according to ASME's style

\subsubsection*{DOI, URL, and eprint} Include DOI numbers when they are available.  URL's may alternatively be given. ASME requests that URLs point to a document's abstract.

Basic support for \texttt{eprint} numbers is also included, generating a url at the end of the citation. The \texttt{archive} type may be specified using the macros \texttt{arxiv, google\-books, hdl, jstore, oclc}, or \texttt{pubmed} (e.g., \texttt{archive=hdl},  \textit{without} braces). Both \texttt{eprint} and \texttt{archive} fields \textit{must} be given. Other root urls may be invoked using \verb|archive = {https://another.url.org/}|.

\subsubsection*{Online Sources} A bibliography entry \verb|@online{..| is included for citation of online sources, such as web pages. A \texttt{url} or \texttt{eprint} with \texttt{archive} must be included. See the examples of use in the \texttt{asmeconf-sample.bib} file. 

\subsubsection*{Date Accessed} The \verb|urldate={..}| field may be used to provide the date on which a given url was accessed. By default, the text printed will be \texttt{Accessed `date',}. The word ``Accessed'' may be changed using the \verb|urltype={..}| field.

\subsubsection*{Conference Location and Date} To specify the city and date of a conference, you can use \verb|venue={..}| and \verb|eventdate={..}| with the entries \verb|@inproceeedings{..| and \verb|@proceeedings{..|

\subsubsection*{Capitalization of Titles} ASME's bibliography style requires that document titles be in title case. The first letters of principal words are capitalized. Do this in the \texttt{.bib} file.

\section[More on math: u\cdot\omega=0]{More on math: $\vec{\mathrm{u}}\cdot\vec{\omega}=0$}\label{sec:moremath}

In most cases, the need for a wide equation can be eliminated by using one of the multiline equation environments defined by 
\texttt{amsmath}, such as \texttt{align}, \texttt{split}, or \texttt{multline}~\cite{amsmath}. The following equation is set with the 
\texttt{multline} environment:
\begin{multline}\label{eqn:energy}
\frac{\partial}{\partial t}\left[\rho\bigl(e + \lvert\vec{u}\rvert^2\big/2\bigr)\right]  + \nabla\cdot\left[\rho\bigl(h + \lvert\vec{u}\rvert^2\big/2 \bigr)\vec{u}\right] \\
 ={}-\nabla \cdot \vec{q} +  \rho \vec{u}\cdot\vec{g}+ \frac{\partial}{\partial x_j}\bigl(d_{ji}u_i\bigr) + \dot{Q}_v
\end{multline}
An example using \texttt{align} appears in Appendix~\ref{appendix:a}.

An experimental package for setting equations that span two columns, \texttt{asmewide.sty}, can be loaded as well, but that code may require hand-fitting around figures, tables, and page breaks. See the examples in~\cite{lienhard2022}. An alternative solution may be to set large equations into two-column-wide tables or figures. 

Math italics are used for Roman and Greek letters by default.  If you want an upright letter in math, you can use the relevant math alphabet, e.g., \verb|\mathrm, \mathbf, \mathsf|:
\begin{equation}\label{eqn:dw}
\vec{F} = m \vec{a} \quad\textrm{or}\quad \vec{\mathrm{F}} = m \vec{\mathrm{a}} \quad\textrm{or}\quad \mathbf{F} = m \mathbf{a} \quad\textrm{or}\quad \vec{\mathsf{F}} = m \vec{\mathsf{a}}
\end{equation}

\subsection{The \texttt{newtxmath} and \texttt{unicode-math} Packages~\cite{sharpe1,robertson2023}} The \texttt{newtxmath} package, loaded by default with \hologo{pdfLaTeX}, includes many options for mathematics, most of which can be called as options to \verb|\documentclass|. For example, the \texttt{upint} option selects upright integral signs (rather than slanted integral signs):
\begin{quote}
\verb|\documentclass[upint]{asmeconf}|. 
\end{quote}  
The option \verb|subscriptcorrection| improves the spacing of math subscripts. Math options are discussed further in the \texttt{asmeconf-template.tex} file.  The \texttt{newtxmath} package is also loaded with the \texttt{[nofontspec]} option.

To get additional symbols in bold math with \hologo{pdfLaTeX}, use \verb|\bm{..}| from the \texttt{bm} package, which is loaded by the class. 

If using \hologo{LuaLaTeX}, the math features of \texttt{unicode-math} are available.  These include commands to select a boldface, upright symbol, \verb|\symbfup{..}| or \verb|\mathbfup{..}|, to select boldface fraktur 
symbol, \verb|\symbffrak{..}| or \verb|\mathbffrak{..}|, and so on.  See the documentation of \texttt{unicode-math} for details~\cite{robertson2023}.

The \texttt{[upint]} option also works under \hologo{LuaLaTeX}.

For longer passages of bold math, you can use \verb|{\mathversion{bold}..}| with either \hologo{pdfLaTeX} or \hologo{LuaLaTeX}: 
\verb|{\mathversion{bold} $A\otimes\mathfrak{F}$ }| gives {\mathversion{bold} $A\otimes\mathfrak{F}$}. Note that the math version must be changed \textit{before} starting math mode.


\subsection{Sans-Serif Greek Letters}
The class file also provides upright sans-serif Greek letters with \verb|\sfalpha| and similar expressions (e.g., $\sfalpha, \sfbeta, \sfgamma, \sfdelta$ \ldots ), in case they are needed. 

Under \hologo{pdfLaTeX} boldface, upright, sans-serif Greek letters can be obtained with \verb|\bm{\sfalpha}|, etc.  The \texttt{newtx} package also includes options that affect whether Greek letters are upright or slanted (see that package's documentation for details).

Under \hologo{LuaLaTeX}, boldface, sans-serif, upright Greek can be obtained with \verb|\sfbfalpha|, etc., or by using \verb|\symbfsfup{\alpha}|.  In the first case, the glyphs are drawn from the Lete Sans Math font, while in the second case, the glyphs are from the TeX Gyre Termes Math font.   Why are two different fonts being used? Unicode does not include medium-weight upright Greek as a component of a serif font (like Termes), although it does include both upright and italic boldface Greek. However, in a sans-serif font (like Lete), Greek letters are sans-serif by default, including medium weight. (You can also invoke \verb|\symbfsfit{\alpha}| for  boldface, sans-serif, slanted type.) 

\subsubsection*{Sans-serif Math Versions} Two additional math versions, \texttt{sansbold} and \texttt{sans} are available in \texttt{asmeconf}.  The former is used by default in captions and section headings.  The latter is available in case you find a use for it. In \hologo{LuaLaTeX}, both versions use the Lete Sans Math fonts. In \hologo{pdfLaTeX}, the glyphs are from the \texttt{newtxsf} package.
  
  
\subsection{Controlling Calligraphic, Script, Fraktur, or BB Fonts}
With \hologo{pdfLaTeX}, the  package may be loaded in the preamble~\cite{sharpe2}.\footnote{As of v1.41, the \texttt{[mathalfa]} class option has been dropped.} This package supports variety of font for calligraphic, fraktur, script, and blackboard bold fonts. For example,
\begin{center}
\verb|\usepackage[cal=euler,frak=boondox]{mathalpha}| 
\end{center}
selects the Euler font for \verb|\mathcal| and the Boondox font for \verb|\mathfrak|. Refer to the \texttt{mathalpha} documentation for details~\cite{sharpe2}.  The \texttt{[nofontspec]} option also supports \texttt{mathalpha}.

Under \hologo{LuaLaTeX}, the \texttt{unicode-math} \texttt{range} function can be used to select such fonts~\cite{robertson2023}. For example, the following code in the preamble would select the Euler Math font for calligraphic, script, fraktur, and blackboard bold fonts:
\begin{quote}\raggedright
\verb|\setmathfont{Euler-Math}[|
\verb| range={cal,scr,frak,bb},|
\verb| Extension=.otf,Scale=MatchUppercase]|
\end{quote}


%%%%%%%%%%%%%%%  ADDITIONAL PACKAGE OPTIONS  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\section{Additional Options for \NoCaseChange{\texttt{asmeconf.cls}}}
The class accepts a number of options in addition to those already described. These options are discussed next.

\subsection{Colored Hyperlinks}
ASME requires that all text be \textbf{in black} when the paper is submitted for publication.  For other uses, authors may
obtain colored hyperlinks with the [\texttt{colorlinks}] option.

\subsection{Final Column Balancing} The option \texttt{[balance]} invokes the the \texttt{flushend} package~\cite{tolusis}.
This package will attempt to give equal height to the two columns on the last page. The performance of this package is sometimes inconsistent (with odd page layout or, very rarely, errors), so use this option with caution.

\subsection{Grid-Style Author Block} The option \texttt{[grid]} invokes ASME's grid-style arrangement of author names. In the \verb|\SetAuthors{..}| command, individual author's names are recognized by the commas that separate them. (To include a comma \textit{in} a name, enclose the name in braces.) Line breaks (\verb|\\|) may be inserted into the address of \verb|\SetAffiliation{n}{address}| as needed. 

Note that ASME interprets the author order in the grid style by reading names from left-to-right in the top row, then left-to-right in each subsequent row.

\subsection{Line Numbers} The option \texttt{[lineno]} invokes the the \texttt{lineno} package~\cite{bottcher}. This option will produce line numbers in the margins. You must run \LaTeX\ \textit{twice} for proper placement of the numbers. Tables, captions, and footnotes will not be numbered.  Line numbers can be helpful for review and editing, but should not be used in your final manuscript. See the documentation of the \texttt{lineno} package for further commands to control line numbering. 

The \texttt{lineno} package is not compatible with the \texttt{flushend} package that makes final short columns the same height. Balancing is automatically disabled when this option is called. 

\subsection{Changing the Copyright Footer} The option \texttt{[nofoot]} will omit the ASME copyright from the page footer. The option \texttt{[govt]} will produce a copyright notice for authors who are employees of the U.\ S.\ Government.  
The option \texttt{[contractor]} will produce a copyright
notice for authors who are employed by a U.\ S.\ Government contractor.
The option \texttt{[somegovt]} gives a copyright notice for the case when only some authors are employees of the U.\ S.\ Government.

The footers are generated with the \texttt{fancyhdr} package~\cite{oostrum} and can be changed using the commands of that package. Only the default arrangement matches ASME's style, however.

In addition, the conference header on the title page can be omitted using the option \texttt{[nohead]}.

\subsection{Archivability:~PDF/A} In June 2022, the \LaTeX{}3 team added support for PDF/A to the \LaTeX\ kernel through the command \verb|\DocumentMetadata{..}|. This approach works with \textit{both} \hologo{pdfLaTeX} and \hologo{LuaLaTeX}. Note that accessible  conformance~(\texttt{a} or \texttt{UA-2} level, a.k.a.\ ``well-tagged PDF'') is still under development by the  \LaTeX3 team.

As of \texttt{asmeconf} v1.41, the legacy options \texttt{[pdf-a]}, \texttt{[pdfapart=]}, and \texttt{[pdfaconformance=]} have been dropped.

\subsection{Typewriter Font Options} This font is the sans-serif \texttt{inconsolata}. By default, the word spacing is variable, but option \texttt{[mono]} switches to monospacing. A slashed zero is the default; option \texttt{[var0]} removes the slash. Option \texttt{[hyphenate]} enables hyphenation. (The hyphenation option is not available under \hologo{LuaLaTeX} with \texttt{fontspec}.)

\subsection{Support for Other Languages}  This package can be adapted to incorporate (or entirely use) languages other than English. See Appendix \ref{appendix:c} for details.


%%%%%%%%%%%%%%%  Nomenclature Environment  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\section{Nomenclature Environment}
A nomenclature environment is included, as illustrated just after the abstract.  Each item in the nomenclature list is entered as \verb|\entry{symbol}{meaning}|.  Optional subheadings can be included as well: \verb|\EntryHeading{Roman letters}|.  The environment includes an optional argument for changing the space between symbols and definitions, 
\verb|\begin{nomenclature}[Xcm]|, where X is a number and cm can be replaced by any LaTeX dimensional unit: pt, in, ex, em, pc, etc. The default value is~2~em.

The title of the nomenclature can be also changed, e.g.\ \verb|\renewcommand*{\nomname}{List of Symbols}|

This brief illustration of an appendix shows the numbering of the appendix and equations. Equations are numbered
consecutively, following those in the paper. Consider $\rho \neq \textrm{fn}(p)$:
\begin{align}
\frac{d\Gamma}{dt} &{}= \frac{d}{dt} \int_{\mathcal{C}} \mathbf{u} \cdot d\mathbf{r}\\
				   &{}= \int_{\mathcal{C}} \frac{D\mathbf{u}}{Dt} \cdot d\mathbf{r} + \underbrace{\int_{\mathcal{C}} \mathbf{u}\cdot d\biggl( \frac{d\mathbf{r}}{dt}\biggr)}_{=\, 0} \\[-2pt]
                   &{}= \iint_{\mathcal{S}} \nabla \times \frac{D\mathbf{u}}{Dt}  \cdot d\mathbf{A}\\
                   &{}= \iint_{\mathcal{S}}  \nabla p \times \nabla \left( \frac{1}{\rho}\right) \cdot d\mathbf{A}
\end{align}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\section[Use with LuaLaTeX]{Use with \NoCaseChange{LuaLaTeX} }\label{appendix:b}

The \hologo{LuaLaTeX} engine is useful with \texttt{asmeconf} in at least three situations:

\begin{description}

\item[Executing lua code directly in your \LaTeX\ file.] With lua code, complicated functions can be plotted or numerical integration can be executed. An example file in the distribution demonstrates this capability~\cite{lienhard2025}. In this situation, you can use the class option \texttt{[nofontspec]} to stay with the \texttt{newtx} fonts. 

\item[Using complex alphabets.] With \hologo{pdfLaTeX}, \texttt{asmeconf} supports Latin alphabets, as well as Cyrillic, Greek, and Vietnamese. If you need scripts such as Arabic, Chinese, or Devanagari, \hologo{LuaLaTeX} with the \texttt{fontspec} package can use fonts available on your computer.\footnote{For English, you \textit{must} have these OpenType fonts (\texttt{.otf}) installed (all are in TeX Live and will be present if your installation is complete and up-to-date): TeX Gyre Termes X, TeX Gyre Termes Math, TeX Gyre Heros, Inconsolatazi4, LeteSansMath, STIX Two Math. For Greek and Russian, the Noto Serif, Sans, and Mono TrueType fonts (\texttt{.ttf}) are used, and those are also in TeX Live. For south and east Asian scripts, the relevant Noto fonts are \textbf{not} currently in TeX Live (go here: \hrefurl{https://github.com/googlefonts/noto-fonts}{github.com/googlefonts/noto-fonts}).}  See the example file in this distribution for more details~\cite{lienhard2021}.

\item[Producing tagged PDF.] Under \hologo{LuaLaTeX} with \texttt{unicode-math} (which loads by default), \texttt{asmeconf} PDF files can meet the PDF 2.0/UA-2 standard using appropriate arguments to \verb|\DocumentMetadata{..}| provided that: a) subfigures are not used; b) any figure files meet the standard; c) the option \texttt{[captionpatch]} is called; and d) language options are used cautiously (some languages are compatible with tagging, but others, such as Japanese and Spanish, currently are not). Tagged pdf is still under development by the \LaTeX{}3 team as of \the\month/\the\year. 

\end{description}

For clarity, \texttt{fontspec} and \texttt{unicode-math} are automatically loaded when \texttt{asmeconf} is run under \hologo{LuaLaTeX}. Those packages require that the necessary fonts are available on your computer.  If you wish to use \hologo{LuaLaTeX} without the features of \texttt{unicode-math} and \texttt{fontspec}, use the class option \texttt{[nofontspec]}. 

Over the long-term, \hologo{LuaLaTeX} will become the preferred engine for using \LaTeX\ (see \href{https://www.latex-project.org/news/latex2e-news/ltnews40.pdf}{\textit{LaTeX\ News}, Issue~40}). Access to \hologo{LuaLaTeX} is different in each \LaTeX\ platform. Check the documentation for your platform to load \hologo{LuaLaTeX}.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\section{Multilingual Support}\label{appendix:c}

ASME publishes in English, but the \texttt{babel} package is loaded for 
users who may wish to include other languages. For example, an author might wish to include an appendix that provides the 
abstract in another language.

When more than one language option is included in \verb|\documentclass[..]{asmeconf}|, English will be 
set as the document's main language. (To choose a different main language, set \texttt{[main=..]}).
If no language options are given, the package defaults to English.  As examples, a passage in German is 
shown in  \selectlanguage{german}\appendixname~\ref{app:pohlhausen}\selectlanguage{english},
%\selectlanguage{french}\appendixname~\ref{app:fourier}\selectlanguage{english}, 
followed by abstracts in other languages.

The input encoding can be utf-8, as for these glyphs:
%% If you have trouble with the next line, your file may not be saved in utf-8 format. You can delete that line to resolve the issue.
\typeout{If you have trouble with the next line, your file may not be saved in utf-8 format. You can delete that line to resolve the issue. Under LuaLaTeX, you can load the fontspec will support these characters if you have the relevant systems fonts installed}%
àáâäæãåā  èéęëêēė  îïíīįì ôöòóœøōõ ûüùúū çćč ł ñń ßśš ÿ žźż.

Fonts similar to Times/Helvetica are used when Greek, Vietnamese, or selected cyrillic-alphabet languages are called as options under {\upshape\hologo{pdfLaTeX}}. Using {\upshape\hologo{LuaLaTeX}}, which loads the fontspec package, many additional scripts are available; see the supplemental notes for such usage~\cite{lienhard2021}. Possibilities include Arabic, Bengali, Chinese, Devanagari (e.g., for Hindi), Hangul (for Korean), Kana (for Japanese), and Tamil. \textit{These options require an up-to-date \LaTeX\ installation.}

The bibliography style, \texttt{asmeconf.bst}, is designed in English and aimed at \hologo{BibTeX}.

\section{Wärmeaustausch und Reibungswiderstand (\NoCaseChange{von} E. Pohlhausen)}\label{app:pohlhausen}
In einer strömenden Flussigkeit sind Wärmeleitung und Wärmekonvektion Vorgänge, die mit der inneren Reibung (oder Impulsleitung) und mit der Impulskonvektion große Aehnlichkeit besitzen. Mathematisch findet dies seinen Ausdruck in dem gleichartigen Bau der Differentialgleichungen, die einerseits für die Temperatur und anderseits für den Geschwindigkeitsvektor in der Flüssigkeit bestehen. Man kann daraus auf eine Beziehung
zwischen dem Wärmeaustanch und dem Reibungswiderstand schließen, die eine strömende Flüssigkeit an einem festen Körper hervorrufen. Dies ist zuerst von Prandtl ausgesprochen und durchgeführt worden, und zwar für turbulente Vorgänge, unter der vereinfachenden Annahme von Wärmequellen und -senken im Innern der Flüssigkeit~\cite{pohlhausen1921}.
