11.2.2. Generating a RFI file

RecurDyn/RFlexGen supports three types of RFI generation methods which is determined by where the FE-mesh data come from. So, it is possible for users to generate a RFI file from a FFlex body, a RFlex body and the Text file (*.dat or *.bdf) by using new functions.

Figure 11.31 RFlexGen dialog box

• Eigen Solver: Performs an eigenvalue analysis by using the Sunshine.

• Input Data: Selects the FE-data type and Interface nodes. 3 types of Mesh Data can be used as Select Flexible Body, Nastran Bulk File, and Sunshine Input File.

• Case Control Settings: Possible to define the normal modes of a RFI file and the units that should be used about FE-Data when generating a RFI file. For more information, click here.

• Output RFI File

  • RFI File Name: Defines an output RFI file name and the path where a RFI file generates.

• Export Input File: Exports a Dynamic Input File without performing an eigenvalue analysis.

Note

The temporary file path is always the same as the output RFI file path. Therefore, the output file path should have a extra space.
