Hello,

I am simulating a 2D vertical axis turbine through Fluent. I am using a sliding mesh technique with 2 interfaces to separate the rotating part where the blades are placed from the stationary domains. The results I get in terms of power coefficient are good enough, but when I plot the contours of velocity magnitude I find that there is some kind of discontinuity between the cells separated by the inner interface. This problem doesn't happen in the outer interface.

I attach a picture of the solution.

Thanks in advance for any help.

I think that your problem is in inner interface definition (maybe, mesh size in both side of interfaces)
Please attach a picture of the mesh.
