Imposing orthogonality to hierarchic higher-order finite elements

Result description

We propose a new class of hierarchic higher-order finite elements suitable for the hp-finite element method discretization of symmetric linear elliptic problems. These elements use shape functions which are partially orthonormal on the reference domain under the energetic inner product induced by the elliptic problem. We present numerical experiments showing excellent conditioning properties of the new partially orthogonal shape functions compared to other popular sets of hierarchic shape functions.
