Dear All, Can you please tell me how to visualize the mass flow rate from CFX post if i am using the variable mass flow given in CFX it is giving me some negative values. Looking forward your valuable reply.

Thanks and Regards Wespl.

Hi,

Negative mass flow means the net flow is in the reverse direction. Isn't that pretty obvious?

Thanks Horrocks, Can you please tell me how to get the mass flow rate from CFX. i thing what i am doing is not a correct method to capture the mass flow rate.

Thanks and Regards

Hi,

You can get mass flow rates as the simulation progresses using a monitor point, and you can also get it from a finished run in CFX-Post using the tools/function calculator.

Both of these methods are discussed in the documentation.

Dear Horrocks, Thanks for your reply, and it is useful for me to take out the results and i would like to know if my boundary condns are Total pr at the inlet and Static pr at the outlet. what can be my soln i took the velocity and it seems to be correct but not the pressure so if i need pr soln what shud be my boundary condn.

Thanks and regards Siva.K
