Hi,

I'm simulating a 3D Pulverized Coal Boiler in Fluent 14.5, and the only problem that I have its that when I do a flux report, the DPM kg/s are not equal to the sum of the kg/s of each injection.

for example, i have 12 coal injections of 1.04167 kg/s (total 12.5 kg/s) and in the report of mass fluxes or the rest of (total mass outlet and inlet) are 11.55 and doesn't change with iterations.

Residuals are OK, and everything is OK.
Enery on, p1 model on, wet combustion model, rossin rambler, K-e model, etc

Any idea?
I'm looking at wet combustion model maybe there is something wrong, I don't know...


thanks!
