Residual based a posteriori error estimators for eddy current computation. (English) Zbl 0949.65113
From the authors’ abstract: We consider $$H (\text{curl};\Omega)$$-elliptic problems that have been discretized by means of Nedelec’s edge elements on tetrahedral meshes. Such problems occur in the numerical computation of eddy currents. From the defect equation we derive localized expressions that can be used as a posteriori error estimators to control adaptive mesh refinement. The fundamental tool in the analysis is a Helmholtz-type decomposition of the error into an irrotational part and a weakly solenoidal part.
