[Solved] Cavity volume as an input (rather than pressure)

Dear all,

I would like to model a closed cavity with incompressible hydrostatic fluid inside.

The cavity is deformed in the interaction between the internal fluid being which is increased in volume by adding new water (at a known rate) and the external elastic interactions. The pressure is being measured. I know how to model the problem using fluid elements, using *static, and cavity interaction, defining pressure as an input. However, I would like to have volume as a control parameter.

I looked around in the manuals but I havent found any straightforward so far. Any ideas guiding me to the right direction?

Thanks a lot in advance...

I have not done that type of FE model for a while, and I cannot think of a simple solution ?.

Let us know if you figure something out!
