Dear all,

I'm trying to mesh a more or less complex structure and right now, I always receive the error message that self-intersection is not supported.

Can anyone explain this error message nearer to me? I don't know how to tackle this problem as I am not quite sure what its cause is.

Thank you.

Hi

most probably your geoemtry is intersecting (even just slightly) in some region(s). Anothe issue when meshing is loops (i.e torus shapes) often the mesher is better off by cutting such topologies into two or more subsystems with internal boundaries

Good luck

I am facing exactly the same problem. I have a very very thin coil embedded inside a solid tube. The meshing always gives out error no matter what I do.
Could you tell which command in comsol is used to accomplish the splitting up topology?
