A Domain Decomposition Method for Time Fractional Reaction-Diffusion Equation [PDF]

open access: yesThe Scientific World Journal, 2014
The computational complexity of one-dimensional time fractional reaction-diffusion equation is O(N2M) compared with O(NM) for classical integer reaction-diffusion equation. Parallel computing is used to overcome this challenge.

A GenEO Domain Decomposition method for Saddle Point problems

open access: yesComptes Rendus. Mécanique, 2023
We introduce an adaptive element-based domain decomposition (DD) method for solving saddle point problems defined as a block two by two matrix. The algorithm does not require any knowledge of the constrained space.

Overlapping Domain Decomposition Method with Cascadic Multigrid for Image Restoration

open access: yesMathematics, 2023
In the process of image restoration, it is usually necessary to solve large-scale inverse problems, where the computational cost is very high for large or high-resolution images.

Parallel efficiency of a boundary integral equation method for nonlinear water waves [PDF]

open access: yes, 1997
We describe the application of domain decomposition on a boundary integral method for the study of nonlinear surface waves on water in a test case for which the domain decomposition approach is an important tool to reduce the computational effort.

Domain Decomposition Spectral Method Applied to Modal Method: Direct and Inverse Spectral Transforms

open access: yesSensors, 2022
We introduce a Domain Decomposition Spectral Method (DDSM) as a solution for Maxwell’s equations in the frequency domain. It will be illustrated in the framework of the Aperiodic Fourier Modal Method (AFMM).

D3M: A Deep Domain Decomposition Method for Partial Differential Equations

open access: yesIEEE Access, 2020
A state-of-the-art deep domain decomposition method (D3M) based on the variational principle is proposed for partial differential equations (PDEs). The solution of PDEs can be formulated as the solution of a constrained optimization problem, and we ...
