Composition schemes for the guiding-center model

Abstract

We present composition schemes for solving non-linear transport equations, like the guiding-center model. This is based on direct and adjoint transport steps. The adjoint steps being implicit, they are replaced by explicit approximated adjoint steps using a given number of fixed point iterations. This does not modify the order of accuracy. Several numerical tests assess the performance of the method.
