strange phenomenon in interFoam

Hi everyone,

Hope you are fine and doing well.

I am trying to simulate flow past a cylinder near free surface with a bed. The simulation looks good at some fist time. However the flow is reflected back upstream when time increase though I set the boundary condition for outlet is inletOutlet for all parameters.

Would you please share with me if you have any suggestions.
Thank you in advance

Hi Nguyen,

Please try the "advective" condition for the velocity at the outlet.
