I am running a simple 2d fsi simulation. it runs well for o to 1s, if i increase time to, say 2s, the solver stops by telling:
Nonlinear solver did not converge.
Maximum number of segregated iterations reached.
Last time step is not converged.
- Feature: Time-Dependent Solver 1 (sol1/t1)

What can i do to avoid this?
I use analytical function to prescribe velocity for solid body as sine function.
how can I avoid this?

Thanks

Hi,

You can try with this approach if your model is time dependent study: www.comsol.com/support/knowledgebase/1127/
