5 years ago Hi @461353349
something went wrong during parsing the results from Calculix. Currently the optimization was tested on ccx (2.8) and ccx (2.15). Maybe the export of the displacements in CalculiX has changed a little bit.
You are familiar with python, so that I would reccomend, that you should clone the repostiroy https://github.com/DMST1990/ToOptixCore
Just run the python script run_optimization*.py Does this run with standard configuration?
In the .json file you need to specify the ccx path
{ "ccx_path": ".\ccx.exe", "work_path": "work", "cpus": 6 }

When I run the "TwoRectanglesStruc.inp", Errors are as following. I donnot know what is the wrong.
