Computational modeling of advanced, multi-material energetic materials and systems
… over time and represent internal solid regions. Approximate Riemann solvers and the Ghost Fluid Method or Overlap Domain Method are used to enforce appropriate interface boundary conditions. Ghost nodes are set by a new local and point-wise node sorting algorithm that decouples these nodes by …

Efficient finite-volume schemes for magnetohydrodynamic simulations in solar physics
… and three spatial dimensions. We introduce a new approximate Riemann solver for the ideal gas MHD equations (MHD-HLLEM) that outperforms all other solvers considered. We present and compare several Riemann solvers that are suitable for the real gas case of an arbitrary equation of state (EOS) …
