A family of low dispersive and low dissipative explicit schemes for ...
? The Poisson equation for pressure is discretized with a compact symmetric stencil. ? The approach is a prerequisite to implement a fast Poisson solver for a ...
A multi-order sub-stencil weighting strategy for discontinuity ...The most upwind stencil is modified to be composed of 4 grid points, while the inner two stencils still use 3 grid points but the ... Compact symmetric Poisson equation discretization for ... - ArchimerStencil computations are very common in scientific codes. Heterogeneous systems achieve good results solving these problems, but their programming is complex ... A new 6th-order WENO scheme with modified stencils - LSECAbstract?We derive and compare several finite-difference frequency-domain (FD-FD) stencils for points on or near a planar dielectric ...
