Hello,
I want to model a 2D cavity that filled with an incompressible fluid in two steps. In the first step the pressure inside the cavity will increase inflate the cavity. In the second step, I want to use the last pressure magnitude inside the cavity from the first step as the initial value and then an external force will be applied to exterior side of the cavity to deform the cavity. I am indenting yo use FSI. My problem how to make the internal pressure changes while the volume kept constant in the second step? If I applied the pressure as load on the internal surface, it will be constant and wont change.
Thanks..
Sam
