FEM_TO_TRIANGLE
Convert a Mesh from FEM to Triangle Format


FEM_TO_TRIANGLE, a MATLAB program which reads FEM files of node coordinates and element connectivity, which define a mesh of a 2D region, divided into triangular elements, and creates a corresponding pair of Triangle files.

These files can be used as input to Triangle for viewing, or mesh refinement.

Usage:

fem_to_triangle prefix
where prefix is the common filename prefix:
