Custom Field Function Question
 
I have a model that I want to run at multiple angles of attack. I want to calculate the magnitude of the v and w components of the velocity (the components of the local velocity perpendicular to the freestream velocity). I know that I can calculate these if I hard code the angles into a custom field function (u=Vy*sinAoA+Vx*cosAoA, v=Vz, w=Vy*cosAoA-Vx*sinAoA), but I have to delete and rewrite the CFF for each AoA I run. Is there any way to get the CFF to look up the AoA from the boundary condition (or at least the velocity components so I can calculate the AoA)?

I appreciate any help.

Thanks, Jason
