What is it about?
Numerical modelling is a very important tool for the investigation of wavefield from the earth's interior and the interpretation of seismic data. We analyze the numerical dispersion, anisotropy numerical behavior and numerical stability of discontinuous Galerkin method with different basis functions for acoustic and elastic wave equations.

Why is it important?
The numerical dispersion, convergence and stability provide criteria for parameter choose in numerical simulation. Therefore, our work can provide an explanation for the numerical dispersion phenomenon when using discontinuous Galerkin methods to simulate seismic wave propagation.
Perspectives
Writing this article was a great pleasure as it has co-author, my phD supervisor, Professor Fu. This article also give me a lot of confidence to explore some more application of discontinuous Galerkin method in geophysics.
