| Abstract: | a new posteriori error estimator and adaptivity approach for electromagnetic field finite element computations are proposed- The problems about the selection of the norm of the error estimator and the discontinuities of fields at the interfaces of various material regions are considered. The method for obtaining the control parameters of mesh adaptive generation is given out. The automatic adaptive finite element analyses for some 2D electromagnetic field problems are realized thought the integration of the error estimator and the fully automatic adaptive mesh generator proposed by the authors. bome examples are provided to show the per formances of the proposed posteriori error estimate and adaptivity approach and the implemented program code. |
