hello hello,
Any help highly appreciated.. please..
Im using a F_FLUX(t,tf) to extract data (mass flow rate) from fluent to a .txt file. x = F_FLUX (t,tf) access data from each elementary face. then I use a auxilliary variable, which sums the values from all elementary cells. looks like: y =+ x;. Now I have a total mass flow rate [kg/s] through a boundary face. But, when i try to compare this value with value accessible in Fluent reports >Report>Fluxes, or >Report>Surface integrals, I get a something totally different. I have no idea why..
Just for completness - simulation is unsteady, I just pick up some converged time step for confrontation..

Any idea? thank you very much in advance..

Probably a typo: y =+ x
If you're using the above atribution with the intent of y = y+x; then is wrong. What it really means is: y = +x; or simpler y = x.
