What is C.V. based finite element method

C-H Kuo

From previous topics on FD vs.FV, Duane metioned the CV based finite element method a better approach for CFD. Can someone make more detailed description on this method?

As I know the major commercial CFD codes for handling multi-million element problems seem all based on FV method. From textbook I know FEM is more accurate than FV; however, FEM suffers from computing speed and large RAM when dealing with large number of elements.

It seems to me that differences among commercial FV codes are: accuracy due to various discretization schemes, the way of solving large sparse linear system, solution algorithm, and customization for specific engineering problem. Otherwise, I cannot expect too radical advantage from a certain code, such as computing speed or accuracy.

Would this CV based FEM achieves both accuracy and speed. I think many are wondering how and why.
