MARY

A method for deriving hexahedral finite elements with lumped mass matrices for 3-D-problems is presented. These elements meet the theoretical conditions for high order convergence, and two numerical examples based on the 3-D scalar wave equation show that this is also the case in practice and that their accuracy is comparable to elements with consistent mass matrices.

## Abstract A Galerkin‐characteristics finite element scheme of lumped mass type is presented for the convection–diffusion problems. Under the weakly acute triangulation hypothesis the scheme is proved to be stable and convergent in the __L__^∞^‐norm. Using the Freefem, we show 2D and 3D numerical

In this article we construct and analyse the performance of various combinations of high order edge elements for the transverse field component with high order node elements for the longitudinal field component. The overall efficiency and mode resolution improve dramatically with high order elements

The Preconditioned Conjugate Gradient algorithms (PCG) are used for solving the matrix equations arising from the Finite Element Method (FEM) with high-order element functions. A vectorizable and a non-vectorizable block preconditioner for use with the conjugate gradient method is presented. The alg
