A FETI-DP preconditioner of discontinuous Galerkin method for multiscale problems in high constrast media
Rui Du, Yunfei Ma, Talal Rahman +1
In this paper we consider second order elliptic partial differential equations with highly varying (heterogeneous) coefficients on a two-dimensional region. The problems are discre…
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…
