High-pressure gas tank

Hi, full disclosure: I have not yet tried FreeFEM. I do have some experience with Abaqus CAE. Just wondering before getting all in, is it possible for FreeFEM to simulate the wall stresses of a pressure vessel as function of an internal pressure? I would think to probably model 1/8 of a tank (gas cylinder). I am interested in resulting dome and wall stresses. Any suggestion is much welcome. Many thanks. Frank

Yes, it si possible, but you havé to explain complète you modèle with équation.
