FabOr is on a distinguished road
Hi all,

i try to programm a vacuum-champer pump out, so there is only one outlet with the BC pressure zeroGradient and velocity fixedValue, because the pump can pump out a defined volume/sec. On all other BC (walls), p and U have both zeroGradient.
but when i run the case with rhoPisoFoam, the pressure icreases instead of decrease. i donīt know why this happen.
Can anyone help me?
