ROY4 Member Roy Join Date: Sep 2017 Posts: 80 Rep Power: 8	hello I'm modeling a bubble column but the pressure that I get from the contours does not seem correct, I have studied the tutorials and some papers. but they couldn't help me solve my problem. the problem is that the pressure increases with height, as we know it is not true because the pressure will increase with height decrease. I MEAN AS WE GO DEEPER IN A FLUID, THE PRESSURE WILL INCREASE, RIGHT? BUT IN MY CASE AS I GO DEEPER THE PRESSURE DECREASES AS I GO UP TO SURFACE IT INCREASES... is there any one here modeling an Eulerian bubble column or have modeled it so that can give me some information? please if any one can help I'm in a serious need... THANKS
