F_AREA with an interface wall
 

Hello world,

I have a nice working udf, which applied to a wall is being used to calculate some useful stuff. But there is a segmentation violation problem if I apply it on a coupled interface wall. I can do a face loop over the faces, adjacent cell search using THREAD_T0 and F_C0 is also working fine, but I can't obtain single face areas since the F_AREA macro returns a [0,0,0] vector for every face.

Any ideas?

Regards,
