I've had the same error for a model with a lot of nodes. I also haven't found a solution. When I run my model and your model I get the following error in the solver output window:
CalculiX execute error: PySide2.QtCore.QProcess.ProcessError.Crashed
But further on in the output Calculix says there are no errors. See the complete output below:
0.0: Run CalculiX...
0.5: Starting CalculiX...
0.5: CalculiX is running...
712.0: CalculiX execute error: PySide2.QtCore.QProcess.ProcessError.Crashed
712.3: CalculiX stopped.

So is this an Calculix error or FreeCAD error?
