triangulation_plot

triangulation_plot, a Fortran90 code which plots a triangulation.

The code reads one file listing the nodes, and a second file consisting of groups of 3 or 6 nodes that make up triangles, and creates an Encapsulated PostScript image of the triangulation.

Usage:

triangulation_plot prefix node_vis triangle_vis

where prefix is the common prefix for the node and triangle files, and will also be used to name the output file:

prefix_nodes.txt, the node coordinates (input);
prefix_elements.txt, the triangulation (input);
prefix.eps, the plot file (output);

and node_vis is an integer defining the node visibility:

0, do not show the nodes;
1, show the nodes;
2, show the nodes and label them.

and triangle_vis is an integer defining the triangle visibility:

0, do not show the triangles;
1, show the triangles;
2, show the triangles and label them.
