hr-adaptivity for nonconforming high-order meshes with the target matrix optimization paradigm
Veselin Dobrev, Patrick Knupp, Tzanio Kolev +2
We present an -adaptivity framework for optimization of high-order meshes. This work extends the -adaptivity method for mesh optimization by Dobrev et al., where we utilized…
Uniform subspace correction preconditioners for discontinuous Galerkin methods with -refinement
Will Pazner, Tzanio Kolev
In this paper, we develop subspace correction preconditioners for discontinuous Galerkin (DG) discretizations of elliptic problems with -refinement. These preconditioners are b…
Scalability of High-Performance PDE Solvers
Paul Fischer, Misun Min, Thilina Rathnayake +8
Performance tests and analyses are critical to effective HPC software development and are central components in the design and implementation of computational algorithms for achiev…
Simulation-Driven Optimization of High-Order Meshes in ALE Hydrodynamics
Veselin Dobrev, Patrick Knupp, Tzanio Kolev +3
In this paper we propose tools for high-order mesh optimization and demonstrate their benefits in the context of multi-material Arbitrary Lagrangian-Eulerian (ALE) compressible sho…
