Dual Reciprocity Boundary Element Methods (DRBEM) are numerical methods to solve Helmholtz equations or modified Helmholtz in a region subject to some boundary conditions. To solve the Helmholtz equation, boundary is discretized into a number of line segment and a number of interior collocation point is chosen. Solutions at collocation points are used to determine solutions at any point in the region or its boundary. In this final project, a DRBEM is applied to solve the time harmonic wave in an isotropic media. To implement this method, MATLAB programs are required. The results are presented as the distribution of wave velocity in isotropic media.
