GP U在SP H方法模拟溃坝问题的应用研究
The application research of GPU in the SPH method to simulate the dam breaking problem
摘要
Abstract
As a mesh-free particle method, the SPH method is very important for dealing with the hydrodynamic problems with strong nonlinear problems. However, following the increase of the particle number, the calculation efficiency becomes a bottleneck for applying the method to the engineering practice. Good acceleration performance can be attained by applying massively parallel computing into the SPH method. In order to study the general parallel purpose of the SPH method, the parallel technology through the use of GPU on the compute unified device architec-ture platform has been used. The convergence and the stability of the computing results generated by GPU have been verified and the computational efficiency of GPU and CPU has been compared according to the computing re-sults by using a numerical example of the two-dimensional dam-breaking problem. The capability, feasibility and high efficiency of GPU computing have been proved by the results which provide important reference channels to in-crease the calculation efficiency of the SPH method.关键词
