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 field reco...

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 Lagrangian ...

A second-order compatible staggered Lagrangian hydrodynamics scheme using a cell-centered multidimensional approximate Riemann solver
We develop a general framework to derive and analyze staggered numerical schemes devoted to solve hydrodynamics equations in 2D. In this framework a cell-centered multi-dimensional approximate Riemann solver is used to build a form ...

3D heterogeneous staggered-grid finite-difference modeling of seismic motion with volume harmonic and arithmetic averaging of elastic moduli and densities.
The problem of a heterogeneous formulation of the equation of motion is analysed and a new 3D fourth-order staggered-grid finite-difference scheme for modeling seismic motion and seismic wave propagation is proposed. A planar-interf...

Staggered explicit-implicit time-discretisation for elastodynamics with dissipative internal variables
An extension of the two-step staggered time discretization of linear elastodynamics in stress-velocity form to systems involving internal variables subjected to a possibly non-linear dissipative evolution is proposed. The original scheme...

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 initially ...
