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-

WebJul 1, 2012 · The curvilinear grid sets up a general curvilinear coordinate system (ξ, η, ζ), the base vectors of which vary from point to point. Note that there are two possible definitions of the unknown velocity vector and the stress matrix in a curvilinear coordinate system. ... To verify that the collocated-grid DRP/opt MacCormack scheme can solve ... Webthe collocated grid system greatly depends on the momentum interpolation method to coupling the pressure and velocities [10]. In details, the momentum interpolation technique adds a term to the discrete fluid continuity equation for ensuring their integrability and regularity.

WebOct 15, 2007 · Unlike the study in the reference, the collocated grid system is used instead of the staggered one. Using staggered grid typically results in stable and robust solutions, as shown in the reference. For general unstructured meshes, however, the staggered methods tend to become rather complex. To avoid this difficulty, an alternative … WebOct 26, 2016 · S.
