Why is it that displacement for a cone is not rotational symmetric for an internal pressure?
A sample model is attached (Creo 3.0) I've brought it back to the bare minimum. 1/4 cone, symmetry, default mesh etc.
It doesn't help if you refine to enormous amounts of elements, Large deformationm analysis makes it slightly better, but it is never right?
Why is that? it should not happen.
How do we solve this?
Extra: I've added a full 360 degree version in Creo2.0 format
