Gerhard Rehm Add-on Modules STEEL RF-STEEL

I am trying to design a cross-section created in SHAPE-MASSIVE in the RF-/STEEL add-on module. However, the cross-section is classified as invalid. What is the cause?

Answer

In this case, it is worth taking a look at the stress points in the cross-section details. If they are not accessible (grayed out), no stress points have been defined in SHAPE-MASSIVE and design is not possible. In SHAPE-MASSIVE, the option 'Stresses by Stress Points' must be activated in the General Data. After recalculating and saving, the cross-section can be designed in the RF-/STEEL add-on module.
