I’m trying to set electrical potentials of conducting cylinders, using boundaries returned by mesh.GetBoundaries(). But this seems to return one less boundary than it should do. What am I doing wrong? Is there a better way to code this?
If everything were correct the cylinders shown by netgen would have uniform colours (yellow, red, blue).
Regards,
Andrew.
