A spatial discontinuous Galerkin method with rescaled velocities for the Boltzmann equation
Gerhard Kitzler, Joachim Schöberl
In this paper we present a numerical method for the Boltzmann equation. It is a spectral discretization in the velocity and a discontinuous Galerkin discretization in physical spac…

A polynomial spectral method for the spatially homogeneous Boltzmann equation
Gerhard Kitzler, Joachim Schöberl
We present a spectral Petrov-Galerkin method for the Boltzmann collision operator. We expand the density distribution to high order orthogonal polynomials multiplied by a Maxwe…
