Reply To: Mass flux calculation
Thank you so much for checking. Excited to hear the new version is out!
You are right. I just realized SuperPlaneIntegralFluxMass2D doesn’t support using a normal. I am now setting the origin (0,ny) and u (1,0) instead. Just curious – is the direction vector u supposed to be along the outlet width? I get a negative flux when u is (1,0) and a positive one at (-1,0). Not quite sure why this happened.
