Hi,

I had to create a velocity profile inlet condition for a simple square inlet in a box domain. So basically the inlet has different velocity values at different points. This results in the airflow entering the domain at an angle (not all normal to the square inlet). Does anyone know how I can find this angle? Can I get an average velocity vector for the air entering the domain somehow? Is there a way to use pathlines to find the angle? Any help is much appreciated, thanks!
