文摘

A new paradigm is presented for finite element analysis in CAD environments. The focus is, firstly, on operating directly with clean-up on the CAD geometry. The focus is, secondly, on establishing efficiently a finite element mesh. Overlapping finite elements are used to achieve these aims. The theory of the new scheme and example solutions are given.
