Bogner-Fox-Schmit元的超收敛
SUPERCONVERGENCE FOR THE BOGNER-FOX-SCHMIT ELEMENT
【摘要】 <正> 1.引言 设Ω是R2的有界区域,考虑如下双调和方程相应的变分问题为:求u∈H02(Ω),使得 A(u,u)=(f,u) Vv∈H02(Ω),
【Abstract】 Superconvergence of the Bogner-Fox-Schmit element for the biharmonic equation is presented. The convergence rate can be increased from two order to four order by the interpolated postprocessing in H2-norm on the general rectangular meshes.
