The solution of large viscoelastic flow problems using parallel iterative techniques
… preconditioner, called the Block Complement and Additive Levels Method (BCALM) preconditioner, is based on treating pressure unknowns separately from the variables velocities and gradients. A pressure preconditioner is constructed from a factor of the Schur complement of the pressures using a …

Parallel Domain Decomposition Preconditioning for the Adaptive Finite Element Solution of Elliptic Problems in Three Dimensions
A novel weakly overlapping two level additive Schwarz domain decomposition preconditioning algorithm is presented which is appropriate for the parallel finite element solution of elliptic partial differential equations in three dimensions. This algorithm allows each processor to be assigned one or …

From efficient high-order methods to scientific machine learning.
… algebraic systems. Secondly, we develop some additive Schwarz methods (ASM) based on solving local patch problems with serendipity elements, allowing us to obtain the same order of accuracy as rectangular tensor-product elements with many fewer degrees of freedom (DoFs). Adapting arguments …

Domain decomposition preconditioners for higher-order discontinuous Galerkin discretizations
… of the implicit scheme. 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 …
