tet_mesh_to_xml

tet_mesh_to_xml, a FORTRAN90 code which reads a file of node coordinates and a file of elements defined by node indices, which define a tetrahedral mesh of a 3D region in terms of 4, 10, or 20-node tetrahedrons, and creates a corresponding DOLFIN XML mesh file.

DOLFIN is the C++ interface to FENICS.

Usage:

tet_mesh_to_xml prefix

• 'prefix'_nodes.txt contains the node coordinates,
• 'prefix'_elements.txt contains the element definitions.
• 'prefix'.xml will contain the DOLFIN XML mesh file.
