Re: FEM keeps giving no results when simulating large mesh.

Thanks. That is also a great solution that maintains the fineness somewhat. Based on your words about the default solver option, I actually tried the iterative solver option and actually got results back! Although the iterative solver seems to take more time as it is a single threaded operation, ti...

Re: Make FEM usable for solid boolean operation

It is possible to convert FEM mesh to solid in FreeCAD if it is what you need. In the FEM wb: - select FEM mesh object (and the result object if the mesh should be deformed, which can be even with some scale according to scripting in https://wiki.freecad.org/FEM_FemMesh2Mesh) - click Mesh -> "F...

Re: FEM and BESO

If you use beso_fc_gui you can select domains by material object (they are internally recognised as elset-s). In the GUI, select one material object for Domain 0, second material object for Domain 1 and untick "As design domain". The optimization should keep Domain 1 untouched, but it will...

is there anyway to ONLY read inp file, solve with calculix and return the result_mesh all in python script? from femtools import ccxtools import sys import subprocess import feminout.importCcxFrdResults inp_file = "/home/fanda/Downloads/tmp/fc_fem/SolverCcxTools/SolverCcxTools/FEMMeshGmsh"...

Re: FEM and BESO

I'm just wondering if it is an add-on that I downloaded in version 20 that isn't in version 19 that could be the problem. Have you heard of anything like this before? If someone mentioned some conflicting addon, I don't recall it. True is that I don't have many addons installed. However, error in l...

Re: FEM and BESO

Can you provide full error message when running beso_fc_gui? What happens if you just open FreeCAD and type import beso_lib to the python console? Does the error appear? For me it works well on windows if I change FreeCAD macro directory, place there some python file and use import. Using spaces or ...

Re: FEM and BESO

Check if you unpacked all files to the FreeCAD macro directory:
beso_conf.py, beso_fc_gui.py, beso_filters.py, beso_lib.py, beso_main.py, beso_plots.py, beso_separate.py
