ABSTRACT: This work characterizes a new acceleration technique for multiphysics problems with highly forward-peaked scattering. The Fokker-Planck equation, which is an asymptotic limit of the transport equation in highly forward-peaked settings, is modified and used to accelerate the transport equation in a high-order/low-order acceleration scheme. The modified Fokker- Planck equation preserves the angular flux and flux moments of the transport equation and can be coupled to multiphysics solves. Coupling the modified Fokker-Planck equation with multiphysics isolates expensive transport sweeps. We observe up to two times speed up in wall-clock time when using this new technique compared to multiphysics coupling using the standard Fokker-Planck Synthetic Acceleration technique.
