Hi all! I have some problems simulating a "Fluid structure interaction". I start from this model www.comsol.com/showroom/documentation/model/361/ . I have tosimulate the mitral valve of te heart so l have changed the structure of internal rectangle. Then l define the boundary condition as in the reference model but Comsol 4.2 return this error:

The following feature has encounteres a problem:
-Feature:Time Dependent Solver 1(sol1/t1)
-Error: Nonlinear solver did not converge.

I already tried to use the smallest mash but i receive the same error

Any ideas?
Thanks

Hi Giovani,
I know you wrote this for a while.
I am wondering if you could tell me if you have achieved to simulate the fsi mitral within comsol.
I am new user of comsol and I am seeking to solve the same problem within comsol.

I would be grateful if you could help me.
thanks
