Reply To: The choice of boundary conditions

[Marcin Nowak]

I want to model the deformations.

"If you're modelling the deformation then velocity inlet and velocity outlet may be suitable. " - You mean, should I try to use the same velocity profile at the inlet and at the outlet?
I dont have however, the velocity measurement at the outlet, only at the inlet, and they may be different due to the deformation and mass accumulation in the domain.
