== IO == :smtk:`WriteMesh ` Writes out a given :smtk:`Collection `, or only the elements that match a given Domain, Dirichlet or Neumann property. This is a preserving process: all information relevant to the mesh is written to file, and subsequent reads from this file should restore the mesh exactly. Supported formats: + MOAB (h5m, mhdf) + Exodus II (exo exoII exo2 g gen) :smtk:`ReadMesh ` Load a given file in as a new :smtk:`Collection ` or part of an existing :smtk:`Collection `. Also supports loading just elements that a given Domain, Dirichlet or Neumann property. This is a preserving process: all information relevant to the mesh should restore the mesh in the same state as when it was written. Supported formats: + MOAB (h5m, mhdf) + Exodus II (exo exoII exo2 g gen) :smtk:`ImportMesh ` Import a given file in as a new :smtk:`Collection ` or part of an existing :smtk:`Collection `. Imports are not preserving processes: all mesh information contained in a file is not guaranteed to be read into the mesh database via `ImportMesh`. Supported formats: + MOAB (h5m, mhdf) + Exodus II (exo exoII exo2 g gen) + VTK (vtk) + SLAC (slac) + General Mesh Viewer (gmv) + ANSYS (ans) + Gmsh (msh gmsh) + Stereolithography (stl) :smtk:`ExportMesh ` Export a given :smtk:`Collection ` to file. Exports are not preserving processes: all mesh information contained in the mesh database is not guaranteed to be written to file via `ExportMesh`.

The exporter will save each Collection using :smtk:`WriteMesh ` with the file type MOAB and extension h5m.
