Periodic condition for wing. -- CFD Online Discussion Forums

pah Guest Posts: n/a	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!
