Hi every one
How can I make a cylinder that inside a box work as jet fan (ventilation system), So I need the jet fan suck the air from the box and back it to the box with different kinetic energy . I am using star ccm+
Thank you.

Thank you.

Create geometry cylinder and cube. Subtract the cylinder from the cube and create a region. For a region - a cylinder, assign an input and output, and so on.

Thanks.... but I need to make the same air that inter the box move forward the cylinder and thrust it again to the box .... I make it by change the interface between the cylinder and the box to Fan interface .... is this correct ?

Whether it is correct or not depends on how the problem is solved. You should have posted a sketch, at least.

Your photo is way is good but it doesn't work with me I need both of the cylinders in the photo below work as jet fans. I use the fan interface to do this is there any other way to make it ?

Dear Abdelrahman KHAMMASH, how about you try to open the User Guide and maybe read the following topics at least:
- "What Are Interfaces?" - p331;
- "Interfaces Overview" - p2157;
- "Fans and Blowers" - p3887.

I'm pretty sure - the community will appreciate that and welcome the qualified engineer and software user who is trying hard to learn. Not the tutorial/example beggar.

And I am sure that if you keep your chatter for your self the community will appreciate that to.
