Test cases for grid-based direct kinetic modeling of plasma flows

Grid-based kinetic models are promising in that the numerical noise inherent in particle-based methods is essentially eliminated. Here, we call such grid-based techniques a direct kinetic (DK) model.

Discussion of Hybrid Atomistic-Continuum Methods for Multiscale Hydrodynamics

It is shown that compressibility is important in determining the choice of a coupling method in hybrid atomistic-continuum methods for multiscale hydrodynamic applications, by relating the molecular integration timestep to the CFL timesteps.

Construction of a Unified Continuum/Kinetic Solver for Aerodynamic Problems
