FEM_TO_TEC <br> Convert an FEM Model to a TEC Graphics File
</h1>
<hr>
<p>
<b>FEM_TO_TEC</b>
is a FORTRAN90 program which
reads three files
defining a finite element model (FEM format) and writes a
TECPLOT ASCII file suitable for display by <b>TECPLOT</b>.
</p>
<p>
The finite element model is assumed to include three items:
<ul>
<li>
Node coordinates, stored in a "node coordinate file";
</li>
<li>
Elements defined by a sequence of node indices, store in an
"element file";
</li>
<li>
Node data, such as finite element coefficients for pressure,
velocity, and so on, stored in a "node data file";
</li>
</ul>
</p>
<p>
<b>FEM_TO_TEC</b> reads these three files and writes an equivalent
TECPLOT ASCII file that can be processed by the <b>TECPLOT</b> graphics program.
</p>
<p>
<a href = "http://www.tecplot.com/">
The TECPLOT home page</a> contains a description of the
<b>TECPLOT</b> program.
</p>

Usage:
</h3>
<p>
<blockquote>
<b>fem_to_tec</b> ( '<i>node_file</i>', '<i>element_file</i>',
'<i>value_file</i>', '<i>tec_file</i>' )
</blockquote>
where
<ul>
<li>
<i>node_file</i> is the FEM node file;
</li>
<li>
<i>element_file</i> is the FEM element file;
</li>
<li>
<i>value_file</i> is the FEM value file;
</li>
<li>
<i>tec_file</i> is the TEC file to be created.
</li>
</ul>
