fem_to_medit


fem_to_medit, a FORTRAN90 code which reads a pair of FEM files defining the node coordinates and elements of a finite element mesh, and rewrites the data as a medit() MESH file.

The code can convert 2D meshes of triangles, or 3D meshes of tetrahedrons.

Usage:

fem_to_medit prefix
where prefix is the file name prefix, so that:
