Trouble writing an .inp file

Post by StressedStudent »

I am currently trying to simulate the heat transfer through a model I created. I am trying to do the following steps:

-Make each component (using the union tool if necessary)
-Create the various materials needed (in this case, silicon, silicon dioxide, chromium and palladium), assigning them their respective components
-Forming a union of all the parts into one unit
-Making a mesh using Netgen (Gmsh for some reason does not work)
-Solving the mesh
-Selecting thermomechanical analysis in the solver attributes
-writing the .inp file (currently where the error is occurring)
-Running CalculiX

When I try to write a .inp file, I get the error message 'write .inp file failed!'. I have produced a heat map before with a slightly simpler model but I refuse to believe my current model is too complicated for FreeCAD. What is going wrong? All videos and tutorials on this topic just show the file getting written without difficulty. I think it would be very useful for the error message to have more information in it future updates to FreeCAD software.

Also, I have noticed a bug in FreeCAD with the analysis tool. When I open a saved project, all the analysis software does not work until I create a new Analysis thread and copy all the materials and solvers into the second thread. This is very strange.

I am currently using MacOS with FreeCAD 0.18-16146.
