%0Computer Program %TMulti-BGK %XThis 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. %AHaack, Jeffrey %Rhttps://doi.org/10.11578/dc.20180411.2 %Uhttps://www.osti.gov/doecode/biblio/10103 %CUnited States %D2018 %GEnglish %2USDOE %1AC52-06NA25396 2018-04-04
