MESH2DUAL is a C program which converts a finite element mesh to a dual graph.
The mesh file is stored in the METIS MESH format, and the resulting graph file is stored in the METIS GRAPH format.
This operation simplifies the use of the METIS partitioning program, which can work directly on the resulting graph. If the same finite element mesh is being used a number of times, it is more efficient for the user to convert the mesh once to a graph, rather than having METIS do it each time.
To convert a finite element mesh file into the graph format preferred by METIS:
MESH2DUAL is part of the METIS family of Multilevel Partitioning Algorithms. It was produced by the lab of George Karypis, who states
"It is our general policy to make these tools available to the research community for use in their own research and/or non-commercial applications."

MESH2NODAL is a C program which converts a finite element mesh to a graph, for further processing by KMETIS or PMETIS.
METIS is a library of C routines for partitioning the nodes of a graph, or the elements of a finite element mesh, or for reordering the variables in a sparse matrix.
METIS_GRAPH is a data directory which contains examples of the graph files used to describe a graph to the METIS family of programs.

MPI is a message passing interface that allows programs to be written for execution on parallel computers.
NEIGHBORS_TO_METIS_GRAPH is a FORTRAN90 program which reads information describing the adjacency relations in a tet mesh, and writes out essentially the same information, but in a format that METIS will accept.
OEMETIS is a C program which reads the adjacency graph of a sparse matrix, stored in METIS GRAPH format, and produces a reordering of the nodes to minimize fill.
ONMETIS is a C program which reads the adjacency graph of a sparse matrix, stored in METIS GRAPH format, and produces a reordering of the nodes to minimize fill.
PARTDMESH is a C program, using METIS, which can partition the elements of a finite element mesh, by working with the dual graph of the mesh.
PARTNMESH is a C program, using METIS, which can partition the elements of a finite element mesh, by working with the nodal graph of the mesh.
