主 题:Adaptive hybridized Interior Penalty Discontinuous Galerkin method a posteriori error analysis H(curl)-elliptic boundary value problems semi-discrete eddy currents equations
摘 要:We develop and analyze an adaptive hybridized Interior Penalty Discontinuous Galerkin(IPDG-H)method for H(curl)-elliptic boundary value problems in 2D or 3D arising from a semi-discretization of the eddy currents *** method can be derived from a mixed formulation of the given boundary value problem and involves a Lagrange multiplier that is an approximation of the tangential traces of the primal variable on the interfaces of the underlying triangulation of the computational *** is shown that the IPDG-H technique can be equivalently formulated and thus implemented as a mortar *** mesh adaptation is based on a residual-type a posteriori error estimator consisting of element and face *** a unified framework for adaptive finite element methods,we prove the reliability of the estimator up to a consistency *** performance of the adaptive symmetric IPDG-H method is documented by numerical results for representative test examples in 2D.
