An Improved Adaptive Finite Element Method for the Simulation of Electromagnetic Field
Basing on the posteriori error estimation and Superconvergent Patch Recovery (SPR) technology, Elena Zhelezina proposed a fast adaptive mesh refinement strategy which can generate the refined mesh for the required accuracy of the solution with only one step of refining the initial mesh. However, this remeshing strategy still generates too many elements which will spend too much memory and CPU time to solve the FEM sparse matrices. In this paper, a new formula to estimate the global error is introduced, and then, a new strategy to calculate every elements refinement degree is presented. Results show that the improved method generates less than half of mesh nodes with only one step of mesh refinement comparing to Elena Zhelezinas method.
