Mass Flow rate
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.

Re: Mass Flow rate

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

Re: Mass Flow rate
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

Re: Mass Flow rate

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.

Re: Mass Flow rate
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
