General Question- Reversed Flow
 

Sometimes when I iterate in Fluent, I see statements like
"reversed flow in x faces at Pressure outlet"
What does it mean? Are there any implications on the solution because of it ?

Hi victoryv,
it' quite usual finding this warning: it means that some streamlines are going backward in the boundary (maybe due to turbulence), it's normal since your simulation has just started!
If you put the boundaries far enough from the last variation in section (in order to let the flow to stabilize) this warning after some iterations should get zero! :)

Sorry for my bad english

Regards

Thank you Bionico. So, literally it does mean "reversed flow". Yeah i did encounter an error once. Had to increase the distance between boundaries.
