Pressure boundary
hi! I use the star-cd program Comet 2.0. I am studying the effect of the surrounding windflow speed on the airflow from the ventilation in an open hold. The internal flow moves towards the back part of the model to go out through a big opening that covers the whole section. This opening is set as a pressure boundary condition, in order to simulate different cases with various surrounding wind speed the pressure at this boundary condition shall be changed. Which Pressure boundary should I choose? the possible ones are: Static; Piezometric; Ambient; Average static; and Outlet Thank you, Phr
