An edge-based smoothed finite element method (ES-FEM) for analyzing three-dimensional acoustic problems

It is well-known that one key issue of solving the Helmholtz equation using finite element method (FEM) is the accuracy deterioration in the solution with increasing wave number due to the “numerical dispersion error”. Such a numerical dispersion error is essentially caused by the “overly-stiff” nat...
