Meshing a complex geometry

AJG

Hi,

I have a complex geometry that I need to mesh, I was told to divide my domain into simpler blocks in order to make easier the meshing, however I am concern about the faces that divide this simpler blocks. how do I treat them as an interface or as an interior?

One other thing is that a few of the smaller volumes HAVE to be mesh using Tri structure which is a different structure than the one used by the rest which is Quad, how can I generate different type of mesh for two faces that are together? what about the boundary that unite them?

thanks for your help
