Bound preserving Point-Average-Moment PolynomiAl-interpreted (PAMPA) scheme: one-dimensional case

R Abgrall, M Jiao, Y Liu, K Wu - arXiv preprint arXiv:2410.14292, 2024 - arxiv.org
We propose a bound-preserving (BP) Point-Average-Moment PolynomiAl-interpreted
(PAMPA) scheme by blending third-order and first-order constructions. The originality of the …

A discontinuous Galerkin spectral element method for a nonconservative compressible multicomponent flow model

R Abgrall, P Rai, F Renac - Journal of Computational Physics, 2023 - Elsevier
In this work, we propose an accurate, robust (the solution remains in the set of states), and
stable discretization of a nonconservative model for the simulation of compressible …

Locally energy-stable finite element schemes for incompressible flow problems: Design and analysis for equal-order interpolations

H Hajduk, D Kuzmin, G Lube, P Öffner - arXiv preprint arXiv:2410.06174, 2024 - arxiv.org
We show that finite element discretizations of incompressible flow problems can be
designed to ensure preservation/dissipation of kinetic energy not only globally but also …

[PDF][PDF] Property-preserving limiters for discontinuous Galerkin discretizations of hyperbolic problems

D Kuzmin, C Lohmann - system, 2022 - iccfd.org
We consider discontinuous Galerkin (DG) discretizations of hyperbolic conservation laws.
The piecewise-constant (P0) version corresponds to a low-order finite volume method …
