Air Flow Direction

I’ve made a simulation of airflow around a building, and I need help with a few things. Why does the airflow circle around my enclosed area, why can’t I see a 3D visual of the model’s output instead of just using a 2D cross-section, and lastly, why is the animation only one frame?


Hi there, there is an issue with the velocity inlet value. According to the orientation of the model, Ux should be negative.

Best regards,

Thank you! That makes sense, but why is the air circling throughout my simulation? I only have Ux with a value.
