The Implications of Second-Order Functional Derivative on Error Estimation in Adaptive Finite Finite Element Analysis for Electromagnetics

摘要

The potential advantages and related costs of using second-order functional mesh discretization derivatives for error estimation in adaptive finite element analysis for eledtromangetics are investigated.Second order indicators are proposed to id inentify and stabilize erroneous frist-order error distributions that arise in unbalanced didcretization regions.Effective combined derivative estimators are introduced and evaluated in practical applications.
