anuprdk New Member anup radhakrishnan Join Date: Jan 2014 Posts: 24 Rep Power: 12	Hi I want to simulate the flow around a 3D cylinder at Re=5x10e5 and determine the characteristic coefficients like drag, pressure etc. I do not have adequate computing resources to resolve a mesh with y+ <100 and hence would need to stick to wall functions. Please advise which Turbulence model and wall function I should choose and an in what range the y+ should be adhering to. Anup
