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 La...

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 buil...

Flow over a given profile in a channel with dynamical effects
The work deals with a numerical solution of steady and unsteady 2D inviscid incompressible flow over the profile NACA 0012 in a channel. The flow is described by the system of Euler equations. Cell-centered finite-volume scheme<...

Cell-centered Lagrangian Lax–Wendroff HLL hybrid method for elasto-plastic flows
The Wilkins hypoelastic model of the solid dynamics is numerically treated by the cell-centered Lagrangian Lax–Wendroff HLL hybrid scheme proposed recently for the Lagrangian hydrodynamics. The scheme is applied to...
