I had similar problems in the past and solved it by defining a customized Gmsh binary path to a manually downloaded Gmsh version (Edit => Preferences => FEM => Gmsh...).
It works! Well done!
Thanks! :mrgreen:

Re: Run Calculix without GUI and read results

Oh, ok, that's a good idea! :D Currently I'm reading FreeCAD/mod/FEM/PyObjects! But that is very difficult to read and understand their scripts like that! I don't find where is the "run calculix" or "ccx.exe"... Do you know if calculix can understand an INP_file generate by Abaqus? INP_file generate...

Run Calculix without GUI and read results

Hi everybody! I developped a python script who execute, with a existing INP_file, inverse method to optimise some parameters and run Abaqus and read results without GUI. For this, I launch Abaqus with os.system("abq6131 job="+inputFileName). It works very well, and I would like to do same with calcu...

Re: Wich version for FEM shell development?

Ok, thank you very much Bernd! This hack is a good idea. :D

Currently we compare Code_Aster and FreeCAD/Calculix to choose which is better for our work.

Re: Element Membrane M3D6

It is exactly what I did, but this message appear : *ERROR reading *SHELL SECTION: *SHELL SECTION can only be used for shell elements. Elemenrt 11 is not a shell element. But I don't understand totally if I must use *Shell Section or *Solid Section. http://www.dhondt.de/ccx_2.12.pdf p445 : *SHELL SE...

Re: ERROR : too many cutbacks

Thanks, that is very interesting! You're right, membrane element must be better in my case. Actually, if I write M3D6 in "*element type", instead of S6, FreeCAD say : *ERROR reading *SHELL SECTION: *SHELL SECTION can only be used for shell elements. Element 11 is not a shell element. Obviously, elem...

Re: ccxInputWriter vs. Faces

We can also notice that when you remesh (but with same boundary condition) in a similar case (biaxial tensile test) freeCAD bug in ccxInputWriter : face 1 and face 3 have same nodes to apply fix constrain. In the same way, I don't understand why with DLOAD lot of node are constrain with negative for...
