Hi everyone.
Ok so I am modeling the semicircular canal of the inner ear which houses the endolymph fluid, maintaining the balance sense of the human body. The problem is there is NO inlet or outlet in the structure. The head movements just generate either a clockwise or anti-clockwise rotation ending up displacing an elastic material called cupula, within the canal.

1) Can I do the simulations using FLUENT, without any inlet and outlet?

2) Also, I need to show the displacement of the elastic material 'cupula( inner ear structure)'. Can I simulate this displacement using FLUENT!?

Please help me if you can! Thanks!
