How does the "Resolve refinement" work?
 

Hey!

I have been trying to create a mesh which has two regions of different mesh density. I created two .uns files and loaded them together to merge them. The merge nodes works good but creates pyramids, which is not what I want. What I think I want is what "resolve refinements" would do to it. But I can't seem to figure out how it works. It gives a warning "This mesh has no couplings".
How do I go about this? It's really getting frustrating now!:confused:
Please help!
