carno Guest Posts: n/a	Hi All I am doing one simple simulation involving pressure calculations. But my problem is that I am getting -ve abs pressures at zones where there are high velocities (region of small gap). I have tried refining the mesh. (all tets). But still I fail to get good solution. Kindly guide. Fluid is water. Pressure difference at inlet and outlet is 60psi(~4bar). What shall I do? thanks
