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
