Lagrange and average interpolation over 3D anisotropic elements
An average interpolation is introduced for 3-rectangles and tetrahedra, and optimal order error estimates in the H1 norm are proved. The constant in the estimate depends "weakly" (improving the results given in Durán (Math. Comp. 68 (1999) 187-199) on the uniformity of the mesh in each dir...
