A mixed, scalable domain decomposition method for incompressible flow

open access: yesComputer Assisted Methods in Engineering and Science, 2017
This work deals with the construction of a mixed and extensible domain decomposition method for incompressible flows. In the scheme proposed here, the solution is sought at the intersection of two spaces, one containing the solution of the Navier-Stokes

An Approximate Schur Decomposition-Based Spatial Domain Color Image Watermarking Method

open access: yesIEEE Access, 2019
In this paper, an approximate Schur decomposition-based spatial domain blind color image watermarking method is proposed to protect the copyright of color images, which has low computation complexity similiar to the watermarking technique in the spatial ...

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 CN-FDTD Method for Analyzing Dispersive Metallic Gratings

open access: yesIEEE Photonics Journal, 2017
In this paper, an efficient domain decomposition (DD) technique is originally introduced into the unconditionally stable Crank–Nicolson finite-difference time-domain (CN-FDTD) method for analyzing the extraordinary optical transmission (EOT ...

Domain Decomposition Method for Maxwell's Equations: Scattering off Periodic Structures [PDF]

open access: yes, 2006
We present a domain decomposition approach for the computation of the electromagnetic field within periodic structures. We use a Schwarz method with transparent boundary conditions at the interfaces of the domains.

Nonlinear Preconditioning: How to use a Nonlinear Schwarz Method to Precondition Newton's Method [PDF]

open access: yes, 2015
For linear problems, domain decomposition methods can be used directly as iterative solvers, but also as preconditioners for Krylov methods. In practice, Krylov acceleration is almost always used, since the Krylov method finds a much better residual ...
