What does this mean?
 

Dear All
I am doing inflow distortion analysis in CFX for single stage axial flow fan.
While running following is showing in between iteration,
what is its significance?


****** Notice ****** |
| A wall has been placed at portion(s) of an INLET |
| boundary condition (at 6.9% of the faces, 4.3% of the area) |
| to prevent fluid from flowing out of the domain. |
| The boundary condition name is: Inlet. |
| The fluid name is: Air Ideal Gas. |
| If this situation persists, consider switching |
| to an Opening type boundary condition instead. |
