Hello Forum,

I am looking for help refining the mesh for a wind turbine. In particular, refining the outer domain mesh of 10mm cells to where it meets the inner domain mesh of 4mm cells. See pics. The second is the same area just zoomed in. I can apply edge refinement to the circle between the two domains but the refinement is applied to the interior of the circle. I have not been able to make it refine to the outside of the circle where it is needed. Is this possible?

[I am using Fluent Meshing through a Workbench project so am not using the standalone Fluent with Fluent Meshing where watertight geometry meshing is had (hope that makes sense, Ansys is a bit confusing with all its softwares and similar namings etc). I prefer to not use Fluent with Fluent Meshing, if possible, considering the learning curve and the short time remaining in my university class.]

It has been a few days since posting. Can anyone at Ansys help?

Hi,

Did you applied shared topology between the two surfaces? You can find more details on shared topology at user's guide: 3.8. Applying Share Topology (ansys.com)

I suggest you to create conformal mesh. A conformal mesh ensures that the nodes on both sides of the interface matches. With a non-conformal mesh, the nodes on one side of the interface does not match the nodes on the other side of the interface. The reason why conformal meshes is preferred over non-conformal meshes: with a conformal mesh there is no (or very little) interpolation at the interface which therefore reduces computational time and ensures higher accuracy of the solution.

Hope this helps you.
