Return the required connectivity in the right mode for the given geometric type of the given entity.

To get connectivity for all geometric type, use Mode=MED_FULL_INTERLACE and Type=MED_ALL_ELEMENTS. You must also get the corresponding index array.

Return the reverse connectivity required by ConnectivityType :

  • If ConnectivityType=MED_NODAL : return connectivity node-cell
  • If ConnectivityType=MED_DESCENDING : return connectivity face-cell

You must get ReverseConnectivityIndex array to use it.
