What is the easiest way to simulate a pillow for the add-on module RF-FORMFINDING?

Answer

In principle, RFEM does not accept identical areas at the same location due to non-uniqueness. In this case, RFEM automatically deletes one of the two faces. Nonetheless, in RFEM, you can create a pillow with shape finding. All you have to do is make sure that in the first input the areas are not in the same place. It is therefore advisable to define the surfaces of the cushion with a Bezier surface and push the inner control points slightly outwards.
