• Easymesh (http://www-dinma.univ.trieste.it/nirftc/research/easymesh/easymesh.html)<br />
After setting up the vertices and the connectivity tables for cells and faces (automatically<br />
done in <strong>SWAN</strong>), <strong>SWAN</strong> will print some information concerning the used mesh, among<br />
others, number of vertices, cells and faces and minimum and maximum gridsizes. Furthermore,<br />
<strong>SWAN</strong> will check at two levels for a possible occurence of badly shaped triangles.<br />
Firstly, the number of triangles that meet at each vertex inside the mesh should not be<br />
smaller than 4 or larger than 10. Secondly, the angles inside each triangle should not be<br />
higher than 143 o . If, at least, one of these two situations occur, <strong>SWAN</strong> will print an error<br />
message.<br />

the necessary grid information is read from file fort.14 as used by ADCIRC.<br />
This file also contains the depth information that is read as well.<br />
the necessary grid information is read from two files as produced by Triangle.<br />
The .node and .ele files are required. The basename of these files must be<br />
indicated with parameter ’fname’.<br />
