Superconvergence of the function value for pentahedral finite elements for an elliptic equation with varying coefficients
Abstract In this article, for an elliptic equation with varying coefficients, we first derive an interpolation fundamental estimate for the P 2 ( x , y ) ⊗ P 2 ( z ) $\mathcal{P}_{2}(x,y)\otimes \mathcal{P}_{2}(z)$ pentahedral finite element over uniform partitions of the domain. Then combined with...
