NX/Nastran can directly generate a RFI file with Stress/Strain shapes. For more information about generating the *.rfi file by NX/Nastran, refer to DMAP Command.
In the case of Normal mode analysis (Modal analysis), NX/Nastran can generate a RFI using the method of MSC/Nastran.
Only following elements are supported in RecurDyn/RFlex.
NX/NASTRAN Element Library
The supported element list is same to MSC/NASTRAN except the CBEND element. Please refer to MSC/NASTRAN Element Library.
Note
A RFI file made by NX/Nastran cannot use the function of generating stress/strain shapes in Stress Shape Interface because the RFI file does not have elements and material information.
