M3hdi New Member Join Date: Aug 2011 Location: Paris Posts: 20 Rep Power: 14	Hi every body, I have a simple question: I run two simulations (flow over a circular cylinder Re = 150 : laminar unsteady case). The first one using icoFoam, and the second one using pisoFoam with turbulence turned off (laminar). The two setups are exactly identical. Results : with icoFoam I got a correct Strouhal number (Sr = 0.156) by plotting the Cl, wheras pisoFoam gives a quite lower value (Sr = 0.0527) !! I am a bit puzzling since I expected that: (pisoFoam + laminar) = icoFoam. Any help please ?? Mehdi
