Spectral Collocation Method for Solving Nonlinear Riesz Distributed-Order Fractional Differential Equations

Mathematics
In this article, we present an efficient and highly accurate numerical scheme that achieves exponential convergence for solving nonlinear Riesz distributed-order fractional differential equations (RDFDEs) in one- and two-dimensional initial–boundary ...

DIRICHLET/DIRICHLET AND DIRICHLET/DIRICHLET-NEUMANN/NEUMANN NON-OVERLAPPING ITERATIVE DOMAIN DECOMPOSITION METHODS

TASK Quarterly, 2008
A new iterative non-overlapping domain decomposition method is proposed for solving the one- and two-dimensional Helmholtz equation on parallel computers. The spectral collocation method is applied to solve the Helmholtz equation in each subdomain based

PSEUDOSPECTRAL APPROXIMATION COMPARED WITH CONTROL VOLUME FORMULATION AND FINITE DIFFERENCES - SOME TEST CASES

TASK Quarterly, 2000
The paper presents comparison of the pseudospectral method with low-order approximation for two test cases. The first test case is quasi one-dimensional supersonic flow through convergingdiverging nozzle for which exact solution exists.
