GMSH_IO
Read and Write GMSH Mesh files
GMSH_IO
is a FORTRAN90 library which
can read and write the files used by the GMSH meshing program.

Related Data and Programs:
DOLFIN-CONVERT,
a Python program which
can convert a mesh file from Gmsh, MEDIT, METIS or SCOTCH format to an
XML format suitable for use by DOLFIN or FENICS,
by Anders Logg.
FEM_TO_GMSH,
a FORTRAN90 program which
reads FEM files definining a 1D, 2D or 3D mesh, namely
a file of node coordinates and a file of elements defined by
node indices, and creates a Gmsh mesh file.
GMSH,
examples which
illustrate the use of the Gmsh program,
a 1D, 2D or 3D mesh generator that can create meshes
suitable for use by the finite element method (FEM).
GMSH_TO_FEM,
a FORTRAN90 program which
reads a mesh data file created by the GMSH program
and writes a pair of node and element files that correspond
to the FEM format.
MSH,
a data directory of examples of MSH files,
the native 3D mesh format used by Gmsh.
TETHEX,
examples which
illustrate the use of TETHEX,
a C++ program which
can read a Gmsh file defining a mesh of triangles or tetrahedrons,
and subdivide the mesh into quadrilaterals or hexahedrons, which
are suitable for use by the DEALII finite element program,
by Mikhail Artemiev.
