This section explains how to generate RecurDyn/Flex Input File (RFI) file from I-DEAS.
This example is a simple plate model. This plate is meshed with thin shell element with steel material property. You can get universal file through super element analysis with prg file. This universal file has FE information which includes node, element, property, material, mass, frequency, mode shape and etc. Mode shape is consisted of the orthonormalized normal modes which are resulted from vibration normal modes and static correction modes.
