Abstract
PurposeIn this paper, the aim is to propose a residual‐based error estimator to evaluate the numerical error induced by the computation of the electromagnetic systems using a finite element method in the case of the harmonic A‐φ formulation.Design/methodology/approachThe residual based error estimator used in this paper verifies the mathematical property of global and local error estimation (reliability and efficiency).FindingsThis estimator used is based on the evaluation of quantities weakly verified in the case of harmonic A‐φ formulation.Originality/valueIn this paper, it is shown that the proposed estimator, based on the mathematical developments, is hardness in the case of the typical applications.
