  1. Domain decomposition preconditioners for higher-order discontinuous Galerkin discretizations

    Diosady, Laslo TiborMassachusetts Institute of Technology2012

    … A minimum overlapping additive Schwarz (ASM) preconditioner and a Balancing Domain Decomposition by Constraints (BDDC) preconditioner are developed for the HDG discretization. An algebraic coarse space for the ASM preconditioner is developed based on the solution of local harmonic problems. …

  2. Domain Decomposition Methods for Convection-Diffusion-Reaction Equations with Finite Volume Discretizations

    Su, YanruUniversity of Kansas2022

    … methods are considered. With overlapping DD preconditioners, we work on a time dependent CDR model. The additive Runge-Kutta (ARK) scheme is used for the time discretization and the fourth-order finite volume is applied for the spacial discretization. With the non-overlapping DD methods, some …
