Exact moment models for conservation laws in phase space
Tileuzhan Mukhamet, Katharina Kormann
Moment equations offer a compelling alternative to the kinetic description of plasmas, gases, and liquids. Their simulation requires fewer degrees of freedom than phase space model…

Structure-preserving finite element approximations of a hybrid relativistic cold fluid-particle model
Tileuzhan Mukhamet, Katharina Kormann
We derive mixed finite element discretizations of a cold relativistics fluid model from approximations of the Poisson bracket that preserve mass, energy and the divergence constrai…
