Dear Fiends,
I m facing problem in convergence for singleSRF case, getting very high velocity, even though continuity Error=0.005, details are as given below,

1. Geometry: Single periodic passage of fan with vortex generators added on on blades. Plz see the geometry image attached below.

2. Mesh: Hexahedral Mesh created in ICEM with blockling, Quiltiy 3X3 determinant=0.7. checkMesh utility shows everything ok. Orthogonality: max-68, avg-27 is check is Ok. total element count 1.59lakh.

3. I set non orthogonality corrector 10 in system / fvsolutions file

Kindly waiting for reply.....

Thank You in advance...

Hi, I'm facing the same problem for getting unreal velocity and pressure, have you solve this problem?
