fem_to_triangle


fem_to_triangle, a MATLAB code 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:
