Hello good people, I am trying to create a simple surface mesh in the pointwise inside a cube. The sphere has six equal domains of equal area. But only any 5 domains out of six can be joined, and the other domain remains ignored. The domains are structured and while joining unstructured mode are switched on. S till the domains are not joined to create a single domain sphere. The reason is to create a single-face mesh for the OpenFOAM simulation and remove all of the connector lines. What can be done in this situation? Is there any kind of convention I need to follow before joining the domains into a single domain?

I have attached the drive link of those file with this post.
