Without AMR, resolved simulations of pellet injection become prohibitively expensive. Simulations using this code were used to investigate the differences and similarities between HFS and LFS pellet injection. It was found that, in qualitative agreement with experiments, HFS leads to better core fueling than LFS launches. On the algorithmic side, in the future, we expect to use a multidimensional upwind method for the hyperbolic fluxes and implicit treatment of the diffusion terms. Finally, we hope to adopt the Jacobian-free Newton–Krylov approach to overcome the temporal stiffness.
