Multi-BGK

Abstract

This code package solves the multi-species 1D-3V BGK kinetic model of Haack, Hauck, and Murillo [J. Stat. Phys., 168, 2017, Phys. Rev. E, submitted, 2017]. This model conserves mass, momentum, and energy and satisfies Boltzmann's H Theorem, i.e. entropy dissipation. Additionally, the collision model matches either the momentum or temperature relaxation rate of the Boltzmann equation. It can be run in 0D-3V and 1D-3V modes.
