Hi guys,

I have a 3d cad model of a medical bellow which I am using to generate negative pressure (NP) to absorb body fluids. What I am trying to do is to enhance the 3d model of the bellow so that I can increase the generated negative pressure by the bellow. I need a way to get the generated (NP) value AFTER changing the 3d model AND according to the material that I set for the part in the program. So I need a simulation program that can achieve these tasks. The result of the simulation will help me to determine the bellow best 3d model so that I can design its blow mold accordingly.

A friend in a different forum told me that to solve this problem I will need a fluid-structure interaction solver, which can also take into account the large deformations of the bellow and the non-linear material law

So as such highly non-linear and computationally problem can I use OpenFOAM? if yes Can you please refer me to related explainational videos or posts so that I can follow the instructions there step by step to achieve the tasks?
If not, can you tell me if there is any open source program that I can use to do these tasks?
