Is there a way to define the size of the computational domain in an external study by using model surfaces? I'd like to have the computational domain resize when the model rebuilds, but I don't like the default size that Flow Simulation generates. Is there a setting that defines the default +/- X,Y,Z offsets from the model? I'm simulating airflow over and through a building located on the ground, so I would like to be able to force the minimum Z to equal zero.
Also, is it possible to define ambient wind speed simply using compass direction and velocity? Changing Vx and Vy every time is a bit cumbersome.
