|This paper presents adaptive kinetic/fluid models for simulations of gases and weakly ionized plasmas. We first describe a Unified Flow Solver (UFS),
which combines Adaptive Mesh Refinement with automatic selection of kinetic or hydrodynamic
models for different parts of flows. This Adaptive Mesh and Algorithm Refinement (AMAR) technique
limits expensive atomistic-scale solutions only to the regions where they are needed.
We present examples of plasma simulations with fluid models and describe kinetic solvers
for electrons which are currently being incorporated into AMAR techniques for plasma simulations.
