Dirichlet-Neumann and Neumann-Neumann Waveform Relaxation for the Wave Equation [PDF]
, 2014 We present a Waveform Relaxation (WR) version of the Dirichlet-Neumann and Neumann-Neumann algorithms for the wave equation in space time. Each method is based on a non-overlapping spatial domain decomposition, and the iteration involves subdomain solves

On condition numbers of symmetric and nonsymmetric domain decomposition methods
, 2020 Using oblique projections and angles between subspaces we write condition number estimates for abstract nonsymmetric domain decomposition methods. In particular, we consider a restricted additive method for the Poisson equation and write a bound for the ...

Domain Decomposition Methods in Feel++ [PDF]
, 2014 This paper presents our ongoing work on building a versatile domain decomposition methods framework in Feel++ that provides expressivity (e.g. closeness to the mathematical language) and efficiency. We display in particular the capabilities of Feel++ regarding Schwarz (non)overlapping and mortar methods.
