chandu143 New Member Join Date: Dec 2011 Posts: 9 Rep Power: 14	I'm presently analyzing fluid flow in hydrodynamic bearings. As some people know at some points the pressure drops below zero. I'm good at fluent but I don't have much idea about UDF's. What I need is a UDF which can analyze pressures in all cells after each iteration and make those pressure values equal to zero which are < 0. I'm going through the tutorials but i can't find relevant example which would be similar to this problem so that I can start working on it. Any suggestions and help would be of great help!
