mesh_display

mesh_display, a MATLAB code which plots the nodes and elements of a polygonal mesh, with optional numbering.

mesh_display() reads two files describing the node coordinates and the elements of a polygonal mesh, and plots them.

Usage:

mesh_display ( 'prefix', node_vis, element_vis )

• 'prefix'_nodes.txt, the node coordinates.
• 'prefix'_elements.txt, the element file

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

• 0, do not show the element;
• 1, show the element;
• 2, show the element and color them.
• 3, show the element and color them, and label them.
