strange flow of pressure boundary adjacent periodic condition
 
Hello
I have a problem in analysis.


xz plane is periodic condition.

and xy plane is pressure outlet.


Obviously, I certainly periodic condition has been set. This can be checked on the contour. But in the adjacent fluid pressure boundary conditions seems strange. Why is Will?

not converge? i checked a residual and physical quantity. these are converged.http://todaystory.net/image/5374/1.JPG

http://todaystory.net/image/5375/2.JPGcondition :
fluid : ideal gas

periodic condition and pressure outlet

Periodic conditions should be assigned for a pair of face zones.
