Results Seem Off For Nozzle Analysis

Working on an analyis for a nozzel that uses an air amplification scheme.


The velocity magitude seems as though it is correct, but the flow rate through seems almost negative.


See pictures below - any thoughts are welcome.

Just a remind the tips at inquiring flow rate in POST processor

- Change result to flow rate  

- Select interested surface(s) only  or face(s) at interested elements

  (Never select nodes)

- Make sure result smooth is disabled


BTW, the negative flow rate is probably correct depending the inflow or outflow at selected surface(s).
