Hi everybody!

I have a little problem in performing the simulation of an autofrettaged pipe.

I need first to simulate the autofrettage pressure and thus the stress so created in the walls, and then to apply the working pressure.

The problem is that I am not able to apply the operative pressure into the yet deformed body.

Is there a way to prevent stress the body or imposing the initial conditions of stress and so on?

Thank you for your kind help to the matter

Best regards
