Hello everyone,

I have a question about Fluent monitors.

In a final of my problem solution, I would like to get such output variable (for example): (Pressure-in - Pressure-out) / Pressure-in. Moreover, I would like to track the convergence of this variable in a process of solving.

In CFX, I can get this by the next manner:
DPP = (areaAve(Pressure)@Inlet - areaAve(Pressure)@Outlet) / areaAve(Pressure)@Inlet

but I don't know, how can I do this in Fluent and is it possible in this program. Maybe anyone can help me.
Thanks in advance.

Best regards,
Delcraft.

diamondx will become famous soon enough
this is done using user defined function ! I don't think it's doable via the regular monitor function in FLUENT

Somebody posted something recently about Custom Field Functions (Fluent User's Guide 33.5). I haven't used these, so I can't vouch for them, but they may work for you.

See 28.16 in the User's Guide for the Convergence Manager.

Hello,

Thank you for your answers.
As I know, it is impossible via Custom Field Functions. I tryed this and without any success.
I hope that UDF can help me. But anyway, it doesn't seem a global problem
