reversed flow in 1270 faces on pressure outlet

tichaona · February 8, 2012, 07:15

Dear collegues

I am getting the message reversed flow in 1270 faces on pressure outlet 23 during calculating solution with Fluent. The same message is coming after every single iteration. Is this an error?

Thank you in advance for any reply.

This belongs in the Fluent section.

No this is not an error, it just tells you that your outlet somewhat acts as an inlet, most likely because of its position relative to the real inlet. You can also get the message early on in the iterative process before the flow field has stabilized.

So I suggest waiting a bit and/or move the outlet if possible (outlets should be far from the inlet and the flow should also be in the outlet normal direction if possible).
