how to connect blocks for the pre-mesh params
 

Hello everyone,

I have a mesh of a rod bundle and a spacer for the periodic conditions with hundred blocks, that I´ll run in fluent.
I would like to know if there are some possibilities to associate more edges of different blocks to get the mesh more fine in the right place like near the walls.
The problem of this mesh is that I have inner walls and the blocks witch are referred to them are difficult to select.

Thank you for your help.

I´ll appreciate all suggestions.
