What causes this error?

Yes, Simon, this is usually an inconsistency in the mesh detected at SPIS/Num level when the SPIS/UI data are passed to Num for simulation instantiation. Usually this is fatal and no simulation can be executed.

I investigated the detail issue one or two times and it was "simply" a tetrahedra lacking!

I don't know what exactly causes that in gmsh or UI, but from my memories changing the characteristic length in the gmsh model might help

Keep me informed of any progress

Does anyone know what causes this error generally? I cant seem to track it down. Obviously something is wrong in my mesh but it meshes fine so i dont know
