GECo: A collection of solvers for the self-gravitating Vlasov equations
Artikel i vetenskaplig tidskrift, 2023

Gothenburgh Einstein solver Collection (GECo) is a collection of solvers for stationary selfgravitating collisionless kinetic (Vlasov) matter. The gravitational interaction may be taken to be either Newtonian or general relativistic. GECo is focused on the solutions which are axisymmetric, meaning that the gravitational and matter fields have a rotational symmetry. In this setting stationary solutions may be generated with the choice of a particular ansatz function for the Vlasov distribution function. GECo allows users to easily introduce new ansatz functions and explore the properties of the resulting stationary solutions.
