Research Abstract |
The applicability of GPGPU was evaluated for the particle methods by using discrete element method as an example for overcoming the difficulty on the computational cost of the particle methods. Hamiltonian Moving Particle Semi-implicit was adopted as the particle method instead of MPS for raising the accuracy of its result, and its feature was evaluated. The development of the hybrid method of HMPS and Finite element method was discussed.
