介绍了一种基于粒子的不可压缩fluidfl算法在图形处理器上的加速。质点方法是基于运动粒子半隐式(MPS)格式，使用对数型加权函数来稳定由泊松方程控制的压力fi场的伪振荡解。标准的MPS格式被广泛地用作求解自由面fl问题、动边界问题、多物理/多尺度问题等的粒子策略。以溃坝flow问题为例，验证了该方法的可行性和有效性。
: An acceleration of the particle-based incompressible fluid flow simulations on GPU using CUDA is presented. The particle method is based on the MPS (Moving Particle Semi-implicit) scheme using logarithmic-type weighting function to stabilize the spurious oscillatory solutions for the pressure fields which are governed by Poisson equation. The standard MPS scheme is widely utilized as a particle strategy for the free surface flow, the problem of moving boundary, multi-physics/multi-scale ones, and so forth. Numerical results demonstrate the workability and the validity of the present approach through dam-breaking flow problem.
