The field of plasma simulations is experiencing significant growth, driven by the development of innovative numerical methods. Recent research has focused on improving the accuracy and efficiency of simulations, particularly in the context of multiphysics systems and nonlinear phenomena. Multirate integration methods, such as multirate Runge-Kutta, are being explored to enable the simulation of complex systems with multiple timescales. Additionally, semi-Lagrangian methods and asymptotic preserving schemes are being developed to address the challenges of simulating plasma behavior in various regimes. Noteworthy papers in this area include the development of a multirate nonlinearly partitioned Runge-Kutta method, which allows for arbitrary nonlinear splittings of the evolution operator, and the proposal of a novel structure-preserving discretization for viscous and resistive magnetohydrodynamics using finite elements. These advancements have the potential to significantly impact the field of plasma simulations, enabling more accurate and efficient modeling of complex phenomena.
