A new adaptive meshing method using non-conforming finite element method

摘要

An adaptive meshing method based on element error estimation followed by suitable mesh refinement is a promising methodology for high-quality electromagnetic FEA. However, achieving suitable mesh refinement process is a hard and labor task, because very often during re-meshing process, an undesired flat-shape elements could be generated which strongly deteriorate simulation accuracy. Therefore, a new kind of mesh refinement method, robust and less laborious, is desired. We propose a new adaptive meshing method employing non-conforming electromagnetic edge FEM. Utilizing the nonconforming FEA results with easy mesh refinements and avoids generating flat-shape elements and low accuracy results.
