Hi,
I am solving the flow in a 2D oscilating tube in a oscillating non-inertial frame of reference. I used the pimpleFoam solver modified to include the Coriolis, Centrifugal and Euler forces. The solver and case study are in attachment. As it can be seen in the attached figure, the velocity near the walls (which are impermeable) is normal to them in some parts. This suggests that the velocity field in non-conservative and the solution is not physically feasible.
Does anyone have any clue for this bug?
Thanks in advance for the collaboration.
