摘要：
The potential advantages and related costs of using second-order functional mesh discretization derivatives for error estimation in adaptive finite element analysis (FEA) for electromagnetics are investigated. Second-order indicators are proposed to identify and stabilize erroneous first-order error distributions that arise in unbalanced discretization regions. Effective combined derivative estimators are introduced and evaluated in practical applications.
