5. GIT validation results
The propagation of acoustic plane waves through the GIT has been computed using the WEM with the newly implemented Myers boundary condition. The computed results presented have been made on a uniform lattice of 65*9 points. Grid convergence of the solution at was checked with finer grids with no appreciable is shown in Fig. 8. The boundary condition types used are the same difference observed. The number of nodal neighbours, M, is taken to be eight for internal grid points, i.e. those immediately surrounding the point in question as illustrated in Fig. 1. Ten shown uniformly spaced wave vectors were used for both q and q so N = 20.
