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