TEC_TO_FEM <br> Convert TECPLOT Finite Element Files to FEM Format
</h1>
<hr>
<p>
<b>TEC_TO_FEM</b>
is a FORTRAN90 program which
reads a TECPLOT file defining a finite element dataset,
and writes a corresponding set of FEM files.

Usage:
</h3>
<p>
<dl>
<dt>
<b>tec_to_fem</b> <i>file.dat</i>
</dt>
<dd>
reads the TECPLOT ASCII file <i>file.dat</i> and creates the FEM files
<i>file.node_coord.txt</i>, <i>file.element.txt</i> and
<i>file.node_data.txt</i>.
</dd>
