Energy balance (buoyancy)
 
Good day everyone.
I have a question. I am creating a "chimney effect" in switchgear by Fluent buoyancy driven flow. Menu Report/fluxes shows this energy balance:

Wall_Heat_Flux +160 W
Convection -12 W
Pressure_Out_Flow -120 W
Pressure_In_Flow -28 W (!!!!)

Problem is in the Pressure_In_Flow. Is possible the value MINUS 28 W, when logically there is only a flow into the chimney but Report says that there is 28 W out of system.

Thanks for answers;-)
