I could not perform your Python script.Gerd wrote: ↑Wed Apr 24, 2019 2:34 pmRight now, this is just a random meshing. The optimizer will create or fill the holes, so that the bending is more following the desired curve (which is not included right now).
What is weird in your picture: The upper row and the right most column have to be fully filled like in my picture. Did you have to change the code in order to get rid of numpy? The filling takes place in line 169 - 170. When these are filled, then there is no problem with calculix, because the contraints are applied at these faces represented by the border volumes. In my case it is running like charm.
I will try next a time dependent force which changes in angle, so that the bending has to follow along like a turning door.
