A 3D posteriori error estimator for FEM solution of electromagnetic problems

We introduce a new method for computing a posteriori error estimator suitable for the finite-element solution of 3D electromagnetic problems. We take into account both the error due to discontinuity on the elements' faces as well as the volumetric error. We demonstrate the efficiency of the error estimator. © 2003 Wiley Periodicals, Inc.
