You are never going to get an answer with a question as general as that. All I can do is refer you to the CFX tutorial examples and if that is not enough go to CFX training.

ya i am getting a message like this in every iteration


+--------------------------------------------------------------------+
| ****** Notice ****** |
| A wall has been placed at portion(s) of an INLET |
| boundary condition (at 1.1% of the faces, 0.8% of the area) |
| to prevent fluid from flowing out of the domain. |
| The boundary condition name is: in. |
| The fluid name is: Fluid 1. |
| If this situation persists, consider switching |
| to an Opening type boundary condition instead. |

Hi murali,

This means that at the inlet or outlet the flow is re-circulating and this creates a wall.
So if you make the inlet longer or narrower, the message should dissappear.

Thanks
Nelly
