Calculation RFEM RSTAB RF-IMP

With RF-IMP, I have generated a pre-deformed equivalent model using a pre-deformed FE mesh. Is the equivalent model now considered for all load combinations, or do I have to enter additional settings?

Answer

The pre-deformed equivalent model is not automatically activated for the load combinations. You have to set this manually in the calculation parameters of the load combination. There, activate the "Extra Options" and activate the option "Initial Deformation from Module RF-IMP".


To activate the option in several load combinations at the same time, use the option to select several load combinations.

The calculation with the pre-deformed FE mesh is performed if the corresponding load combinations will be calculated according to second-order or large deformation analysis.
