Hi, everyone! I useds Fluent to simulate the airflow in a small domain and the inlet boundary is velocity inlet (0.25m/s), ouflow as the outlet bondary. In the iteration, there are no reversed flow, but at the 12th iteration, reversed flow occured and solution is converged at the 97th step. I am not sure if the soulution can be reliable because of the reversed flow. The inlet is revised from a triangle (0.007m*0.007m*0.007m). I am not sure the reason of the reversed flow. Dose somebody expain my question? Thank you so so much!

Regards!

Inlet is the green surface at the bottom, outlets are the red surfaces at the side.

First of all, I think the color of Inlet face is blue, are Blue Green Color Blindness ?

Secondary, The reversed flow is Ok, it is just used to converge.
