I have generated a pre-deformed equivalent model using RF‑IMP by means of a pre-deformed FE mesh. Is the equivalent model considered for all load combinations nov, or do I have to make further settings?

Answer

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

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 the second-order or the large deformation analysis.
