Hello everybody, I am running an unsteady case and I want to access from my udf the mean velocities. Is there a macro for this, because I could not find it in the manual pages?

Thank you! Dragos

Hi Dragos, the macros you need seem not to be available in FLUENT.

They are not documented and I've never been able to find them looking into the FLUENT header files.

Regards, ap

I got the answer from a pro: mean u velocity: U = SV_STORAGE_R(c,t, SV_U_MEAN);

The same for v, w and p. For rms values: urms = SV_STORAGE_R(c,t,SV_U_RMS)

I hope those of you who need this information, will find this answer helpfull.
