I'm trying to simulate an elastic pipe using fsiFoam from foam-extend project. Using the following boundary conditions:
U:
inlet - fixedValue;
outlet - zeroGradient;

p:
inlet - zeroGradient;
outlet - fixedValue;

I've got a back-reflection from the outlet boundary during my simulation. I guess that this happens because of not correct boundary condition at the outlet of the domain.

Does anybody know what type of boundary condition I have to use to fix this issue ?

Hi, was a solution found to this issue? Having the same issue

Unfortunately, no

Hi,

have a look at this boundary condition: https://openfoamwiki.net/index.php/H...dary_condition.

Kind regards,
