Mass Balance in CFX5.7

KKA

Hey Guys

Please, do anyone knows how to obtain both negative and positive mass flow separately at a 2D plane in CFX5.7 post? Thus, say, for a 2D plane, there is backflow occuring at the plane, do anyone knows how to get the estimate of backflow that is occurs at the plane, since if you use the "massflow" function it only gives the overall which I presumed it includes both incoming and outgoing flows in the plane.

A quick response to this will be much appreciated. Thanks a lot!!
