Greetings,

I'm trying to simulate a 2d VAWT case using sliding mesh in Ansys fluent. The problem is that after 2 or 3 rotations, The solver diverges, and the reason is that there is deformation in the boundary layer cells, which is confusing. I would be glad if anyone could help me with this matter. I use the check mesh option before starting the transient run, but there is no problem with the mesh; the problem occurs after the rotor zone rotates and the Inflation layer cells deform when using the Sliding mesh Technique.
