High-order staggered Lagrangian hydrodynamics (II) : the artificial viscosity and hourglass control algorithm
Zhiyuan Sun, Jun Liu, Pei Wang
In this article, we investigate the artificial viscosity and hourglass control algorithms for high-order staggered Lagrangian hydrodynamics(SGH), as proposed in~\cite[Sun et al., 2…

A Thermodynamically Consistent High-Order Framework for Staggered Lagrangian Hydrodynamics
Zhiyuan Sun, Jun Liu, Pei Wang
We present a consistent high-order staggered Lagrangian hydrodynamics framework designed to reconcile an underlying disparity in existing curvilinear formulations: the mismatch bet…
