MEDIT_TO_FEM <br> Convert Mesh Data from MEDIT to FEM Format.
</h1>
<hr>
<p>
<b>MEDIT_TO_FEM</b>
is a MATLAB program which
reads a mesh file created by the MEDIT program
and writes a corresponding pair of node and element files that correspond
to the FEM format.
</p>
<h3 align = "center">
Usage:
</h3>
<p>
<blockquote>
<b>medit_to_fem</b> <i>'prefix'</i>
</blockquote>
where <i>prefix</i> is the common filename prefix so that:
<ul>
<li>
<i>prefix</i><b>.mesh</b>, the MEDIT file to be converted;
</li>
<li>
<i>prefix</i><b>_nodes.txt</b> will be the FEM node file created by the program.
</li>
<li>
<i>prefix</i><b>_elements.txt</b> will be the FEM element file
created by the program.
</li>
</ul>
