non-conformal grid?
 
Due to the fact that I have got major problems with growing pyramids from my structured domains into the unstructured area ( I use gridgen), I decided to split those quad elements, and grow thetrahedrals from them.

Now the domains aren't connected nicely anymore (hanging edges, nodes are still matching) and I have to use the non-conformal grid option in Fluent to overcome. I haven't found until now (also not on this Forum) any major drawbacks of the non-conformal grid option (except sometimes partioning problems). Probably there are some unforseen disadvantages by using this method. Who can help me...
