April 2, 2012, 14:30	3D Circular Cylinder -LES - Pressure Problems	#1
u50mb9 New Member Michael Join Date: Mar 2012 Posts: 6 Rep Power: 14	Hi there. I'm modelling a 3D circular cylinder suspended from the roof of a channel through LES. Problem is my pressure coefficients tend to be really small numbers. I am using PISO and PRESTO! I have tried to reduce URF's significantly but to not much avail. Any suggestions? I'm new to FLUENT so may have done an obvious error
