ANSYS ICEM CFD Mesh to Gambit
 

I am reciving the following error message when trying to import my mesh from ANSYS to Gambit. It is a 3d mesh and the solver is NASTRAN.

ERROR: Error encountered while reading the header information. Gambit is unable to import utility fe2ram -d3 -tNASTRAN -oFIDAP7

Anyone have any suggestions or ideas about this?
