In this article, we construct new higher order finite element spaces for the approximation of the two-dimensional (2D) wave equation. These elements lead to explicit methods after time discretization through the use of appropriate quadrature formulas which permit mass lumping. These formulas are constructed explicitly. Error estimates are provided for the corresponding semidiscrete problem. Finally, higher order finite difference time discretizations are proposed and various numerical results… Expand

The dispersion properties of two types of explicit finite element methods for modelling acoustic and elastic wave propagation on tetrahedral meshes are analyzed to give an indication of which method is the most efficient for a given accuracy, how many elements per wavelength are required for agiven accuracy, and how sensitive the accuracy of the method is to poorly shaped elements.
