Compared to the conventional high-order staggered-grid finite-difference method (C-SFD), the time–space domain dispersion-relation-based high-order staggered-grid finite-difference method (TS-SFD) can ...

FDModBiotCyl.jl simulates seismic wavefield by solving Biot dynamic poroelasticity equations using a staggered-grid finite-difference method. It assumes azimuthally symmetric wavefields in a ...

This software simulate seismic wave propagation by solving equations of motion with constitutive equations of elastic/viscoelastic medium by finite difference method (FDM) under message passing ...

Abstract: To optimize the dispersion of the fundamental weaker hybrid implicit explicit in the finite-difference time-domain method, a lower dispersion method is proposed by optimization parameters. A ...

What Are FEM, FDM and FVM? FEM, FDM and FVM differ from one another in important ways. Understanding these distinctions is key to selecting the method most appropriate for your purposes. The ...

This contribution proposes two third-order numerical schemes for solving time-dependent linear and non-linear partial differential equations (PDEs). For spatial discretization, a compact fourth-order ...

Atmospheric aerosol particles cool Earth’s climate by serving as cloud droplet seeds. This cooling effect represents both the single most uncertain and the largest negative radiative forcing. Cloud ...

Finite Element Analysis, or FEA, is the simulation of a physical phenomenon using a numerical mathematic technique called the Finite Element Method, or FEM. This process is at the core of mechanical ...
