Over a three-month period, J.B. Bell enhanced the AMReX-FHD/FHDeX repository by developing and stabilizing features for the DK hybrid simulation. Bell integrated external potential support, enabling more realistic particle initialization and advection under external fields, and improved boundary condition handling. Using C++ and Fortran, Bell addressed numerical stability and data consistency by recalculating stochastic flux averages and refining particle refluxing, particularly under periodic boundaries. The work focused on high-performance computing and parallel simulation, resulting in more reproducible and production-ready scientific simulations. Bell’s contributions demonstrated depth in numerical methods and particle-based modeling, directly supporting advanced research scenarios in FHDeX.
