二阶问题的一个三维类Wilson元

Quasi-Wilson Element in 3-dimensional Space for Second-order Problem

基于二维的类Wilson元 ,构造了一个用于求解三维二阶问题的类Wilson元 .证明了它对任意的六面体正则剖分是收敛的 ,并且给出了相应的误差估计 .

Based on the 2-dimensional quasi-Wilson element,the quasi-Wilson element in the 3-dimensional space with application to second-order porblem is presented.It is proved that it is convergent for arbitrary hexahedron regular subdivision in 3-dimensional space,and its error estimate is obtained.
