A Spectral Finite Difference Method For Simulating Large In this chapter we propose to compare finite element, finite difference, and spectral methods. Abstract this work evaluates the suitability of the finite difference methods and the pseudo spectral methods for validating the pulse propagation problem in an optical fiber, which is modeled by the nonlinear schrödinger equation (nlse) represented in a classical electromagnetic version. This study confirms this, and proceeds by comparing a fourier ps implementation (based on a longitude latitude grid) with one using spherical harmonics. for similar resolutions, both these versions are found to be of similar accuracy. In this paper, we will compare and contrast two important and popular approaches – the pseudo spectral method and the finite difference method. in the finite difference (fd) method, the governing equations are solved by approximating the derivatives using finite differences. First, the study introduced the theories of random media and two forward modelling methods. second, it compared the simulation results of two methods on fault model. then the authors established a complex metal ore model, added random media and compared computational efficiency and precision. In this review, we provide an overview of some of the important numerical methods for solving pdes in the con text of continuum mechanics. for complex heterogeneous media imaging, these local equations are better suited than integral equation methods (hohmann 1983).
