Analysis of a New Harmonically Enriched Multiscale Coarse Space for Domain Decomposition Methods
Martin J. Gander, Atle Loneland, Talal Rahman
We propose a new, harmonically enriched multiscale coarse space (HEM) for domain decomposition methods. For a coercive high contrast model problem, we show how to enrich the coarse…
Edge based Schwarz methods for the Crouzeix-Raviart finite volume element discretization of elliptic problems
Atle Loneland, Leszek Marcinkowski, Talal Rahman
In this paper, we present two variants of the Additive Schwarz Method for a Crouzeix-Raviart finite volume element (CRFVE) discretization of second order elliptic problems with dis…
Additive average Schwarz method for a Crouzeix-Raviart Finite Volume Element Discretization of Elliptic Problems with Heterogeneous Coefficients
Atle Loneland, Leszek Marcinkowski, Talal Rahman
In this paper we introduce an additive Schwarz method for a Crouzeix-Raviart Finite Volume Element (CRFVE) discretization of a second order elliptic problem with discontinuous coef…
Additive Schwarz preconditioner for the general finite volume element discretization of symmetric elliptic problems
Leszek Marcinkowski, Talal Rahman, Atle Loneland +1
A symmetric and a nonsymmetric variant of the additive Schwarz preconditioner are proposed for the solution of a nonsymmetric system of algebraic equations arising from a general f…
