krembil New Member Marijo Join Date: Jan 2011 Posts: 12 Rep Power: 15	Hi, I am running crosswind DES simulation of box bluff body(vehicle). I have two inlets and two outlets. Inlet velocities are set so yaw angle of the wind is 20. How to set reference values for area, velocity, and length? Also, how to set force vectors? If it was simulation with only headwind, force vector for drag coeff. is (1 0 0) if wind velocity is in x direction and lift coeff. is (0 1 0)? Thank You!
