FabOr Member Join Date: May 2010 Posts: 33 Rep Power: 16	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 don´t know why this happen. Can anyone help me?
