[Tex/LaTex] How to write journal in Latex using Elsevier class files

Question

I am writing a journal in latex using the template files provided from Elsevier website.

Here is the starting code:

\documentclass{jfm}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{subfig}
\usepackage{epstopdf}
\usepackage{amsmath}

\begin{document}

\newtheorem{lemma}{Lemma}
\newtheorem{corollary}{Corollary}

\title{Satisfying Continuity Equation for Incompressible Flows to Machine    Zero}

\author
{
Shashank Mishra\aff{1}
\corresp{\email{mishrash@mail.uc.edu}},
\and 
Shabaan Abdallah\aff{1}
}

\affiliation
{
\aff{1}
Department of Aerospace Engineering and Engineering Mechanics, University of       Cincinnati, Cincinnati, Ohio, 45220
}

\maketitle

When I compile this, it says on the top "this draft is created using the Latex style file belonging to the journal of fluid mechanics".

Is this fine or do I need to somehow remove this?

Answer 1

\documentclass[prodtf]{jfm}

but I suppose that it will not work. A lot of packages are required which may be only present for the publisher when it runs your document.
