Exporting Siimulation (COSMOS) meshes into NASTRAN?

I am running both Solidworks simulation 09 and NASTRAN tosolve design problems, and I get very different answers from eachsoftware (static and modal runs). I would like to export thesimulation (COSMOS) meshed model into NASTRAN to track down wherethe discrepancies are; NASTRAN can read in COSMOS files.....but howwould I do this from Simulation? is there a "save as" in simulationwhere I can export to NASTRAN?

Help!
