Hello, I’m using the simple wind analysis with terrain template. There is a problem creating the Domain for a wDir different from 0 and 180. The box seems not to be created (the box-shaped domain component just defines the terrain without the box). As a consequence, the meshing fails. Any idea about this issue? Thanks!
