[dynamic]

Hi,
I'm trying to run a simple model of the a 2D VAWT.

I have setup a mesh interface between my rotating and static domains, with a periodic boundary condition of rotation type. and this automatically creates additional boundary conditions of "rotation-side1-wall-rotating_edge" & "rotation-side2-wall-static_edge"

however after I run my model, there is discontinuities in the flow field between the two domains (see attached image). my rotating domain is 2x times the diameter of the rotor.

I have edge sizing on both edges of the domains so they match up.

is it these additional wall boundary conditions that are automatically created that is causing my discontinuities?

any advice would be created appreciated.

Thanks
