摘要

本文采用有限差分法(FDM)和光滑粒子流体力学(SPH)相结合的方法来模拟行人的疏散过程。利用基于fdm的快速行军方法，确定了任意两点间最短路径对应的电势分布。利用势分布对行人流的偏微分方程模型进行求解。我们通过模拟来讨论我们提出的方法的定性有效性。

HYBRID ANALYSIS OF PEDESTRIAN FLOW BY FINITE DIFFERENCE METHOD AND PARTICLE METHOD

We develop a hybrid method using the ﬁnite difference method (FDM) and the smoothed particle hydrodynamics (SPH) to simulate evacuation of pedestrian. A distribution of potential that corresponds to the shortest path between arbitrary two points is determined by the FDM-based fast marching method. Using the potential distribution a partial differential equation model of pedestrian ﬂow is solved by the SPH. We conduct simulations to discuss qualitative validity of our proposed method.
