Description
| - 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 introduced by Caramana et al. Namely, momentum equation is discretized by means of subcell forces and specific internal energy equation is obtained using total energy conservation. The main contribution of this work lies in the fact that the subcell force is derived invoking Galilean invariance and thermodynamic consistency. The cell-centered velocity - a supplementary degree of freedom - is solved by means of a cell-centered approximate Riemann solver. Numerical tests are presented in order to assess the efficiency of this approach.
