Languages: {#languages align=”center”}

MESH_IO is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version.

ICE_TO_MESH, a C++ program which reads a NETCDF file containing an ICE dataset and rewrites the information as a MESH file.

MESH, a data directory which contains examples of MESH files, which can be used to define the geometry of a finite element mesh in 2D or 3D, using triangles, quadrilaterals, tetrahedrons or hexahedrons.

MESH_TO_ICE, a C++ program which reads the ICE dataset information from a MESH files and rewrites it to a NETCDF file.

TRIANGLE_TO_MESH, a C++ program which reads the NODE and ELE files created by TRIANGLE to describe a triangular mesh, and writes a corresponding MESH file for input to MEDIT.
