Outlet Boundary Condition
 
Hi,

I simulate an air jet with CFX 5.5. Assumptions: - axisymmetric

- compressible

- subsonic everywhere

- Inlet: total pressure and static Temperature

- Outlet: static pressure (atmospheric pressure)

After convergence (res_max < 1.0e-3), i notice that the oulet boundary condition is not respected. What can I do to impose this static pressure outlet ?

Thanks for your help. Francisca.

Tighten up your convergence, 1e-3 MAX is very loose. Try 1e-4 or 1e-5.
