3D staggered Lagrangian hydrodynamics scheme with cell-centered Riemann solver-based artificial viscosity
This paper proposes the development in 3D of a staggered Lagrangian hydrodynamics simulation code by means of an artificial viscosity force using a cell-centered approximate Riemann solver coupled with a piece-wise linear velocity f...

Comparison of staggered and cell-centered Lagrangian and ALE hydrodynamical methods
Three Arbitrary Lagrangian-Eulerian codes are compared on a set of test problems. Code CHIC is based on cell-centered Lagrangian scheme while codes ALE-INC and PALE are based on staggered Lagrangian scheme. Pure Lagrang...

Curvilinear high-order Lagrangian hydrodynamic code for the laser–target interaction
The laser--target interaction for high-intensities of the laser is very numerically demanding problem, since the dynamics of the process is very rapid. The classical Lagrangian hydrodynamic codes suffer from the progressing distorti...

Some cell-centered Lagrangian Lax–Wendroff HLL hybrid schemes
Lagrangian hydrodynamics is treated by the Lax–Wendroff method with the dissipative fluxes in the HLL form, including both artificial viscosity and artificial energy flux. The symmetry of results for the Noh problem on a Cartesian m...

Conservative high-order time integration for lagrangian hydrodynamics
This work develops novel time integration methods for the compressible Euler equations in the Lagrangian frame that are of arbitrary high order and exactly preserve in nonconservative form, that is, common for staggered grid hydrodynamic...

High-order curvilinear finite element magneto-hydrodynamics I: A conservative Lagrangian scheme
Magneto-hydrodynamics is one of the foremost models in plasma physics. The classical Lagrangian methods are typically limited to the low orders of convergence-order non-ideal magneto-hydrodynamics, where a multi-dimensional...

Staggered Lagrangian discretization based on cell-centered Riemann solver and associated hydrodynamics scheme
The aim of this work is to develop a general formalism to derive staggered discretizations for Lagrangian hydrodynamics on two-dimensional unstructured grids. To this end, we make use of the compatible discretization that has been i...
