MOAB File Format

The file format for MOAB meshes comes from the file specification for DAGMC meshes. These files are in the native .h5m format, which is an HDF5 file containing the mesh itself along with associated metadata. In lieu of reproducing the entire specification here, we refer the reader to the DAGMC file specification.
