[Tex/LaTex] Remove title in nomenclature

Question

I am using the nomencl environment within the elsarticle class to produce an overview of mathematical variables used in the paper. As this nomenclature should be part of the appendix, I would like to suppress its title.
I have found how to change nomenclature titles, but not how to remove it altogether. Here is what I have so far in my TeX Code:

\documentclass[authoryear, review]{elsarticle} %preprint
\special{papersize=210mm,297mm}
\usepackage{nomencl} 
\makenomenclature 
\RequirePackage{ifthen}
\renewcommand{\nomname}{This is the title that should not appear}
\begin{document}
    Bla bla
\begin{frontmatter}
\end{frontmatter}
\section{Section example}
This is my text, where variables appear.
\nomenclature[1]{$\mu$}{Example variable}
\appendix
\section{Definition of model variables}
\printnomenclature[0.9in]
\end{document}

If I just use \renewcommand{\nomname}{}, LaTeX produces a large gap where the title used to be, which also does not look nice.

Thank you very much for any hints or pieces of advice!

Best

Answer 1

nomencl package uses \thenomenclature with this code

\def\thenomenclature{%
  \@ifundefined{chapter}%
  {
    \section*{\nomname}
    \if@intoc\addcontentsline{toc}{section}{\nomname}\fi%
  }%
  {
    \chapter*{\nomname}
    \if@intoc\addcontentsline{toc}{chapter}{\nomname}\fi%
  }%
 ... % and some more code not relevant for this solution

i.e. there is either a \section*{\nomname} or \chapter*{\nomname} command. which should be avoided here.

If the intoc option is used, the \addcontentsline should be omitted as well, but this was not requested.

\documentclass[authoryear, review]{elsarticle} %preprint

\usepackage{xpatch}
\special{papersize=210mm,297mm}
\usepackage{nomencl} 

\xpatchcmd{\thenomenclature}{%
  \section*{\nomname}% Look for `\section*... etc.
}{% Replace it by 'nothing'
}{\typeout{Success}}{\typeout{Failure}}


\makenomenclature 
\RequirePackage{ifthen}
%\renewcommand{\nomname}{This is the title that should not appear}
\begin{document}
    Bla bla
\begin{frontmatter}
\end{frontmatter}
\section{Section example}
This is my text, where variables appear.
\nomenclature[1]{$\mu$}{Example variable}
\appendix
\section{Definition of model variables}
\printnomenclature[0.9in]
\end{document}
