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