Hi, there. I met a problem with solving 2-D pressure vessel probs using axisymmetric Solid 42. First I got the negative radius warning which stopped the solving process. Now I changed elements' x-axis making sure they were all positive. Pressure was applied on inner surface line. After solving, the shape wasn't defored at all. What boundary conditions should I add? I know that the outer surface is orce free but I don't know how to specify it in ANSYS. Would anyone please advise me about this kind of problem? Thanks a lot!
