TRIANGLE_TO_MEDIT <br> Convert TRIANGLE Node and Element Files to MEDIT Mesh File.
</h1>
<hr>
<p>
<b>TRIANGLE_TO_MEDIT</b>
is a C++ program which
reads a pair of node and element files created by the TRIANGLE program
and writes a corresponding Mesh file suitable for viewing with the
MEDIT program.
</p>
<h3 align = "center">
Usage:
</h3>
<p>
<blockquote>
<b>triangle_to_medit</b> <i>prefix</i>
</blockquote>
where <i>prefix</i> is the common filename prefix so that:
<ul>
<li>
<i>prefix</i><b>.node</b> contains the coordinates of the nodes;
</li>
<li>
<i>prefix</i><b>.ele</b> contains the indices of nodes forming each element.
</li>
<li>
<i>prefix</i><b>.mesh</b> will be the MEDIT Mesh file created by the program.
</li>
</ul>
