Hi everyone,

Im doing a set of simulation with different wind directions through a building. Meanwhile, for each direction I need to rotate the domain(cubic several times larger than the building), does anyone have better idea that dont need to change the mesh and can simulate different wind direction?


My first thought is to use two inlets in xz and yz plane, but it turns out the velocity is larger at the diagonal and decays to the edges(not uniform)

My second thought is add a momentum source, but i dont know if i need to change the direction, how much i need source i need to add.
