Abstract
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.
