fem_to_gmsh


fem_to_gmsh, a MATLAB code which converts FEM files representing a 1D, 2D, or 3D mesh into a GMSH mesh file.

The FEM files include a node file, which simply lists the coordinates of each node, and an element connectivity file, which lists, for each element, the indices of the nodes that define it. Either 0 or 1-based indexing can be used when referencing the nodes.

Usage:

fem_to_gmsh prefix
where prefix is the common filename prefix:
