Wrong Velocity Boundary Condition
 
1 Attachment(s)
Hello:),

I am new in Ansys Fluent, but my problem should be simple.
I just want to simulate an airflow through and around a pipe. I build this with the symmetry boundary condition, so i just use the quarter of the pipe. I also use the viscous model: laminar.
Now my problem: At the interface from the flow and the pipe should be the velocity 0, but this isnt the case (picture). Around the pipe, i have the right boundary condition, but not in the pipe.

Can someone help me? Do you need more information?
