Development of a parallel multi-term Boltzmann solver using the Qubus framework — •Christopher Hinz1, 2, Markus Becker2, Detlef Loffhagen2, and Michael Bonitz1 — 1ITAP, Christian-Albrechts-Universität zu Kiel, Leibnizstr. 15, 24098 Kiel — 2INP Greifswald, Felix-Hausdorff-Str. 2, 17489 Greifswald
Electron transport and rate coefficients required by hydrodynamic plasma models
are frequently obtained by solving the stationary and homogeneous Boltzmann
equation of the electrons.
The present contribution reports on the status of the implementation of such
a Boltzmann solver by means of the parallelization framework Qubus [1].
Qubus particularly assists in the development of parallel codes for
multiple platforms without compromising the ability to easily adapt the code
to new requirements.
The considered solution procedure is based on a multi-term expansion of the
electron velocity distribution function in Legendre polynomials [2].
The speedup of the solution procedure provided by Qubus finally enables the
direct coupling of the kinetic equation with hydrodynamic plasma models.
