Hi,

Can anyone please suggest a journal about vortex breakdown occurring in a rotating cylinder done using Ansys??

Hi all,
Thanks for this very good tutorial, it helped me a lot !

I managed to make the circle rotate, but now I realize there is a discontinuity at the circle interface with the outer fluid domain.
The fluid present in the Rectangle surface doesn't enter in the circle, as if the circle were a rigid body. This is strange as circle surface and circle edge are specified as interface.
That may come from the mesh or the setup.
-Is there a step in the mesh creation that could be corrected to have circle an outer fluid domain relationated ?
-Or maybe it comes from the boudary conditions :
afer creating the periodic boudary condition with the mesh interface tool, wall conditions appear, and seam to be relationated to the circle.

Any advice on this ?
Thanks !
