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.

以离散元法为例，分析了GPGPU在粒子方法中的适用性，以克服粒子方法计算量大的困难。为了提高粒子法计算结果的精度，采用了哈密顿移动粒子半隐式法代替MPS法，并对其特点进行了评价。讨论了HMPS与有限元混合方法的发展。
