Pseudospectral vs. Finite Difference Methods for Initial Value Problems with Discontinuous Coefficient
An initial value problem with piecewise constant coefficients is considered. The accuracies for both finite difference methods and the pseudospectral method are analyzed, and a modification of the initial value problem is suggested. The modified problem is shown to have the same temporal period as the original problem does, and a second order accuracy is obtained for the pseudospectral method a...
متن کاملImplicit Extrapolation Methods for Variable Coefficient Problems
SUMMARY Implicit extrapolation methods for the solution of partial diierential equations are based on applying the extrapolation principle indirectly. Multigrid tau-extrapolation is a special case of this idea. In the context of multilevel nite element methods, an algorithm of this type can be used to raise the approximation order, even when the meshes are nonuniform or locally reened. Here pre...

متن کاملComparison of Finite Difference- and Pseudospectral Methods for Convective Flow over a Sphere
For modeling convective flows over a sphere or within a spherical shell, pseudospectral (PS) methods are in general far more cost-effective than finite difference(or finite element) methods. 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 foun...
متن کاملEffects of geometrical and geomechanical properties on slope stability of open-pit mines using 2D and 3D finite difference methods
Slope stability analysis is one of the most important problems in mining and geotechnical engineering. Ignoring the importance of these problems can lead to significant losses. Selecting an appropriate method to analyze the slope stability requires a proper understanding of how different factors influence the outputs of the analyses. This paper evaluates the effects of considering the real geom...
