negative pressure in mixing tank

vidhya · April 26, 2011, 07:20

hi i am simulating single phase flow in a stirred tank. i am getting negative values for pressure in the tank domain. why does it happen?
does that indicate that the flow is taking a turn in the opposite direction? if its so then near the walls also i should have negative pressure as the fluid flow diverges at the vicinity of baffles...
i am more confused with it...

Anything can happen when you do not do an accurate CFD model. For further hints see:
