A mass-energy-conserving discontinuous Galerkin scheme for the isotropic multispecies Rosenbluth--Fokker--Planck equation
Takashi Shiroto, Akinobu Matsuyama, Nobuyuki Aiba +1
Structure-preserving discretization of the Rosenbluth-Fokker-Planck equation is still an open question especially for unlike-particle collision. In this paper, a mass-energy-conser…

Eigenstructure-preserving scheme for a hyperbolic system
Takashi Shiroto, Akinobu Matsuyama, Nobuyuki Aiba
A hyperbolic system must have a set of linearly independent eigenvectors and corresponding real eigenvalues. In numerical simulations, however, the eigenvalues can be complex becau…
