41: DMMoabOutput - Output the solution vectors that are stored in the DMMoab object as tags
42: along with the complete mesh data structure in the native H5M or VTK format. The H5M output file
43: can be visualized directly with Paraview (if compiled with appropriate plugin) or converted
44: with MOAB/tools/mbconvert to a VTK or Exodus file.
46: This routine can also be used for check-pointing purposes to store a complete history of
47: the solution along with any other necessary data to restart computations.
49: Collective
51: Input Parameters:
52: + dm - the discretization manager object containing solution in MOAB tags.
53: . filename - the name of the output file: e.g., poisson.h5m
54: - usrwriteopts - the parallel write options needed for serializing a MOAB mesh database. Can be NULL.
