I tried using a different solid to perform FEM on and it seems to work albeit there was a warning message. I wonder if there could be something wrong with the original solid.
Definitely there are. I took your OP example file and ran a geometry check with BOP enabled
. There are some errors that probably lead to your final problem. They come from your array that has intersecting shape.
The good news is that this isn't a big issue, and everything get solved by setting "Refine = true" in the object properties.
Then gmsh still complains (AFAIK it always complains
) but it generates a good mesh that can seamlessly be used for FEM analysis.
Eg. below I fixed the feet and pushed 50 kg it's too much
I'll attach the FreeCAD file but I have to clean it so it is accepted by the forum.
=> EDIT : I had to remove the results from the FEM analysis !
Beware that refining the shape will mostly break the existing FEM constraints and material attachment.
