I tested a little bit further, im a bit confused about the boundary conditions...

The boundary condition in p_rgh, fixedFluxPressure or fixedValue for the outlet are critical.

At the...

Hello,
i have a problem with my multiphase laminar simulation (Water, Air).

The simulations runs smooth, until water comes near the outlet (after 5-6 seconds), then the velocity's at the outlet...
