Superconvergence Recovery for the Gradient of the Trilinear Finite Element

Article Preview

Abstract:

For a second-order elliptic boundary value problem in three dimensions, we use an interpolation postprocessing technique to obtain recovered gradients of tri- linear elements over regular meshes. Further, superconvergence of these gradients are proved.
