kingjewel1 Senior Member Join Date: Jul 2009 Posts: 260 Rep Power: 18	I'm modelling flow past a surface mounted cube using the SAS model. Is there a reason why I can't see any inlet perturbations using the Vortex Method (N=1000) in the flow field upwind of the cube? I've run it for 100s and looks smooth as RANS. I'm super confused. Any thoughts?
