Be aware that the workaround affects the mesh region mechanism. Selecting the original solid instead of the compound filter part, gmsh does not create the mesh anymore and states: Solid <Solid object at 0x55e4db172200> not found in: <CompSolid object at 0x55e4dc2402c0> Problem: For the geometry of t...

Hello, I am sorry that I have open this topic again. I am unable to reproduce the tutorial (https://www.freecadweb.org/wiki/FEM_Shear_of_a_Composite_Block) since I upgraded to Freecad 0.18. I cannot add the inner cube as mesh region even though I have the selection add on. The steps I take are: 1) C...

I read though the wiki and the post fenics solver . Then I tried to figure it out on my own with these steps: 1) Create a simple g...
