10.15. MDF Export

To obtain the more accurate stress/strain recovery results for all animation frames after simulating a RFlex model, it is necessary to create a MDF file which contains both modal coordinate results and the rigid motion results about each RFlex body in NX Nastran. And then, the user can get the stress/strain recovery results as the OP2 or PCH file type in NX Nastran by using both a BDF file which is the bulk data file contained several information such as elements, nodes, and so on and a MDF file.

RAN and RPLT files should be generated to use this function.
