چکیده
Seismic modeling plays an important role in geophysics and seismology for estimating the response of seismic sources a given medium. In this work, we present MATLAB-based package, FDwave3D, synthetic wavefield seismogram 3D anisotropic media. The simulation is carried out using finite-difference method over staggered grid, it applicable to both active passive surveys. code package allows incorporation arbitrary source mechanisms offers spatial derivative operators accuracy up tenth-order along with different types boundary conditions. First, methodological aspects are briefly introduced. Then, has been tested verified against analytical solutions obtained homogeneous model. Further, numerical examples layered overthrust models presented demonstrate its reliability.

A Closed-Form Solution for Two-Dimensional Diffusion Equation Using Crank-Nicolson Finite Difference Method
In this paper a finite difference method for solving 2-dimensional diffusion equation is presented. The method employs Crank-Nicolson scheme to improve finite difference formulation and its convergence and stability. The obtained solution will be a recursive formula in each step of which a system of linear equations should be solved. Given the specific form of obtained matrices, rather than sol...

متن کاملA fast eikonal equation solver using the Schrödinger wave equation
Abstract. We use a Schrödinger wave equation formalism to solve the eikonal equation. We show that a solution to the eikonal equation is obtained in the limit as ~ → 0 of the solution to the corresponding linear Schrödinger equation. The Schrödinger equation corresponding to the eikonal turns out to be a generalized, screened Poisson equation. Despite being linear, it does not have a closed-for...
