If you have mesh in native hd5 MOAB format, VTK, Cubit, gMesh, you can use such mesh directly. If you using mesh in MED format used by code-aster, you need to convert mesh into native MOAB hdf5 format.

If you would like run analysis on multiple-processors you need to partition mesh. You can do that using mofem tool to do that.
