Hi All

I have a strange result for a simple cantilever made of aluminium round tube. This is part of an assembly.

With the beam mesh the result matches manual calculation, with solid mesh the result is far above theoretical value (normal bending stress). I guess this has a simple explanation and solution, however I couldn't find out myself. Similar problem with rectangular cross section gives acceptable values.

I really appreciate if someone takes a look and give me advice.

Regards,
