Hi
I need to calculate flow rate through a plane ( is not vertical or horizontal) in CFD post (CFX Post)

I want to use expression areaInt( Velocity.Normal vector )@plane.

But I dont know how to calculate normal vector of the plane?

How can I obtain x,y,z of normal vector of plane (for inner product with velocity)?

Regards
