N2 - An interpolation operator is proposed using the cubic grid solution of order O(h4), h is the mesh size, of the Dirichlet problem for Laplace’s equation in a rectangular paralellepiped. It is proved that when the boundary functions on the faces of the rectangular parallelepiped are from the Hölder classes C4,λ, λ ∈ (0, 1), and their second and fourth derivatives obey compatibility conditions implied by Laplace’s equation on the edges, the solution obtained by the constructed operator also has fourth-order accuracy with respect to mesh size.
