Collocated grid system

WebIn this paper, we extend the curvilinear collocated-grid finite-difference method, which has been developed in the study of seismology, to the 2D electromagnetic simulation of ground penetrating radar (GPR). The method combines curvilinear coordinate and collocated grid, so it can better describe the geometry of the irregular interfaces than traditional finite … Webstaggered grid system, and it is proved that it can enhance convergence rate to a great extent. In this study, the CLEAR algorithm is extended to a collocated grid system to test its feasibility. To fulfill the fundamental requirement for eliminating the decoupling problem between velocity and pressure and making the solution inde-
