iamed18 Member Edward Leonard Join Date: May 2012 Location: Calumet, MI Posts: 31 Rep Power: 14	I'm looking to model a wind tunnel in which the sides are all freestream velocities with freestreamPressure boundary conditions. However, when using the models from the CFD-Online wiki Code: http://www.cfd-online.com/Wiki/Standard_k-epsilon_model something goes awry and my results make no physical sense (speeds on the order of Mach 1.45, for one). My setup is: freestream velocity of 10m/s in the $\hat{y}$ -direction vehicle situated 0.5m above "ground" on the x=0 wall (extending to x=1), and 7m long in direction of wind Geometry: 6mx25mx7m Can someone assist me with choosing boundary conditions for the vehicle, freestream sides, and ground?
