flowRateOutletVelocity not suitable for unsteady cases (pisoFoam)
Dear all, I believe that the boundary condition flowRateOutletVelocity is not suitable for unsteady cases (pisoFoam). The way it is written (proportional correction) allows convergence to be reached while iterating, but for piso algorithm you have to converge at each time step. Proportional correction can eventually be in contrast with CFL limitations as well. What do you think?
Best regards
