Simulation of pneumatic muscle in comsol

Hello all,
........................................................................................................................................................................................
I want to simulate an artificial pneumatic muscle which has a simple cylindrical geometry initially. When the muscle is inflated with fluid/air…it will expand in the midsection (inflate in transverse direction) causing to contract in longitudinal direction. I was wondering if “Fluid structural interaction” can be used for this purpose. If not what are the options?
....................................................................................................................................................................
Another thing is, the domain would have and inlet without any outlet. The fluid would accumulate inside the volume causing it to inflate in transverse direction producing a contraction in longitudinal direction. I would really appreciate any guidance or suggestion from the community.
