Hello guys .. im solving nasa rotor 37 single blade with rotationaly periodic boundary conditions .. i am using inlet and outlet pressure boundary condition .. the grid is 1.5 million .. the y plus is varying from 10 to 100 .. the problem is not converging at all .. i tried to reduce the cfl to 0.01 .. could someone help me with the problem!!!

Hi
How did you set periodic boundary condition? maybe you set translational periodic.
Regards

no .. its rationally periodic with periodic angle 10 deg
