Problems importing a MED mesh created in SALOME

Using SimScale CAD & Meshing
5

Hi @ggiraldof ,

Thanks for your insights again. After a long, long, long… strugge I have managed to upload a mesh. An interesting point I learnt is that the names given to the groups of bodies and faces MUST NOT contain spaces otherwise the simulation crashes before starting to simulate. I leave the information here since it can be useful for anyone else in the future (even for myself, actually…).

Now I have another problem… The solver stops giving this error message:

The solution matrix is singular. This may be caused by an unconstrained rigid body motion, a physical contact definition with open gap in a nonlinear static analysis or incoherent material parameters.

I bet that the second cause pointed out in the message is the one that is causing the crash, but I don’t know how should I proceed to solve it. Besides, looking into the log I found a message that I don’t really understand and may be of interest.

I leave the link to the project here, just in case anyone can give me a hand with that.

Thanks in advance!

Best,
