In the framework of accurate and efficient segregated schemes for 3D cardiac
electromechanics and 0D cardiovascular models, we propose here a novel numerical …

Abstract In this work, Entropy-Stable (ES) schemes are formulated for the multicomponent
compressible Euler equations. Entropy-conservative (EC) and ES fluxes are derived …

Abstract Entropy-Stable (ES) schemes, specifically those built from Tadmor (1987)[54], have
been gaining interest over the past decade, especially in the context of under-resolved …

In this work we examine a multigrid preconditioning approach in the context of a high-order
tensor-product discontinuous-Galerkin spectral-element solver. We couple multigrid ideas …

Traditional adjoint variables grow exponentially for turbulent chaotic flows. Most proposed
methods (for example. ensemble adjoint, shadow-based, and unstable-subspace-based …
