Hi there,

I'm currently researching the SW Flow Cartesian based meshing system for part of my dissertation (Thesis), and am struggling to ascertain exactly how this process is carried out. I have gone through the available white papers on the subject, together with the technical reference PDF, but if you know of any further documentation that might help get a better understanding I would be grateful. 

The question here is simply: in the creation of the cartesian based mesh, surely hanging nodes are created where refinement occurs; if they are indeed created, how does the software deal with them?

Anything on this subject would be of great help to me, many thanks in advance.

*edit* I have focused far too much on the concept of structured cartesian meshing, that I overlooked the fact that SW Flow solves with cell-centres which, correct me if I'm wrong makes the above question invalid. As such, let me update the question to suit:

Due to the nature of cartesian based meshing, hanging nodes are created when refinement occurs. However, in the case of approximations of governing equations using the cell-cantered finite volume method, as seen in SW Flow, do similar issues occur to hanging nodes (or including hanging nodes) ? If so, how does the software content with them?
