How to get volume flow rate of a section?
 

My case is incompressible flow. I get the result by 2 ways.

1. I divided the model into two parts. After finish calculation, I read Mass Flux and put one part in a new cset then use post-> flux sum-> zone.

2. Read velocity and density. Use 'spoint curs' to select the section. Use 'intergrat cset' to get A*VN.

Can somebody tell me what's the difference between these two method? The answers are different. Thank you very much.

They were probably different most likely because the location for "spoint curs" was different from your previous "zone." Try to control (write down) the spoint and snorm.
