I am modeling an evaporation process in horizontal pipe with constant heat flux. I recevied a message "fluent reversed flow in xxx faces on pressure-outlet" the xxx corresponding to a number that keeps increase with the iteration increase. What this means? Could any one help?

What this message is saying is that there is flow going back into your domain from the outlet. For certain problems this isn't necessary an issue. However, if you are expecting all your flow moving out of the domain then this is an issue. You can try extending your outflow domain to make sure that it is far enough away for the region of interest, and all the flow is unidirectional.

More detail about your geometry and set-up will be needed to identify what is causing this flow characteristic.
