Does SolidWorks Flow Cartesian based mesh result in 'hanging nodes'?

Question asked by Joshua Hurrell on Feb 3, 2021

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?
