Superconvergence Analysis of the Nonconforming EQrot1 Element for Nonlinear Moisture Migration Equation
摘要
Abstract
The nonconforming EQrot1 element was applied to a kind of nonlinear moisture migration equation . The supercloseness property was obtained by using mean‐value approach and two special properties of this ele‐ment :(I) the consistency error is one order higher than its interpolation error in the energy norm when the ex‐act solution belongs to H3 (Ω) ;(II) the interpolation operator is equivalent to its Ritz‐projection operator .Fur‐thermore ,through interpolation post‐processing technique ,the global superconvergence result was derived .关键词
