Creating separate mesh in one diagram
 

Hi,

I am very new in Star CCM+ and right now I am trying to create separate meshes in one diagram (see attachment).

1. The outer region have structured mesh.
2. The gap region of three cylinders has unstructured mesh.
3. The neighboring region of each cylinder has homogeneous encrypted structured mesh of 10 layers.

I have been trying but couldn't make it. Any help would be humbly appreciated.
Thanks.

You may be able to do this by creating 3 separate regions with interfaces between then and assigning different mesh continuum to them. But again as mesh originate from the surface is star-ccm, so exact structural mesh may not be possible for outer region.

Instead best solution is meshing in some other software like Hypermesh or so and then importing .msh or .case file to CCM. Importing .msh will directly forms region. Hope this helps.
