A least-squares based nodal scheme for cell-centered Lagrangian hydrodynamics

13 Jan 2020 Wang Chuanjin Luo Hong

This paper presents a new and efficient nodal scheme for cell-centered compressible flows in Lagrangian formulation. A single pressure and the velocity at cell vertex are computed by the nodal solver in a least-squares sense, and both variables are used to evaluate the numerical flux across the cell interface...
