Default Periodic condition for wing.

Hi all!

I am simulating a 3D wing by using "Periodic conditions". The flow is simple with inlet and outlet flow, and Periodic for two ends of the wing. With using "Specify Pressure Gradient = 0" for Periodic Bc at Steady State solution.

For the some first iterations, the results on the wing are reasonable. However, after ~1500 interations the results show a spanwise vortex appears near the periodic Bc.

So, Anybody can suggest me any idea how to solve this problem?

Thanks in advance!
