Accelerating Polyhedral Discrete Element Method with CUDA
The Astronomical Journal, 2023 This paper presents an efficient CUDA-based implementation of a nonspherical discrete element method where irregular particles are described by using polyhedrons. Two strategies are employed to exploit the parallelism of the numerical method.
