Hello.

I need to calculate the mass flow through a cilyndrical surface in CFD-Post, but I want to get only the mass flow entering into the surface, and exclude what comes out of it. IS it possible? If it is, how do I do it?

You could integrate the velocity vector with massFlowAveAbs

Or do a conditional statement on the velocity vector to only get the positive bits and integrate that.

Thanks for your reply, Glenn.

Theoretically I know what I have to do, but I wish to know how to implement that on CFD-post... Is it via CEL, command line, etc...
