structural calculation

[marcofa]

I tried to make a torsion calculation of a pipe, but I get a fungus deformed that leaves me very perplexed.
Can someone tell me where I'm wrong?
Thank you.

you can find the answer, for example, in the last publication of claudio gianini. It is not a mistake, it is a peculiarity of the method (fem).
mistakes in discretting a tubular element with tetrahedral elements. if you just want to use tet elements make a mesh much less woolly.

the default mesh are 25 x sagitta 4
if I make 6 x sagitta 1 is even worse
What do I do?

I have no idea, I don't use catia, but I know the method. It is clear that the tubular was discrete quite badly.
