Hi,

I am trying to mesh a cylinder look domain by the structure mesher with a radial pattern like the picture attached.

Any help is highly appreciated. I tried the directed mesh option but the mesher does not recognize the circles as the edges for the source surface.

Best,
A E

Star-CCM doesn't really do structured mesh. Directed meshing is as close as you can get. If it isn't getting close enough for your liking, you will need to resort to a 3rd party meshing software and import the mesh.

Thanks for your reply MBdonCFD. Yes, I am using the directed mesher on Star-CCM+, however I am not able to mesh the source surface by the auto mesher option (patch mesh). Do you think I should use an existing mesh for this purpose? Any help is really appreciated.

Best,
Amir

You can make that type of mesh if it is what I think it is - is the center hollow? i.e. no mesh there?

If you need a center, the directed mesher can do that, but you have to make a square block in the center of the circle, so your final mesh will not look like the one you posted.

If you want a structured mesh you can't source it from any other mesher than the patch mesh.

Thank you very much for your reply. Yeah, I finally used a revolved rectangle to generate the directed mesh.
