本文是由两部分组成的系列文章的第二部分，通过几个测试用例分析了SP物理的效率，并说明了它的性能。这里详细分析了SPH技术的一些内在特征，如链表的使用和限制的检查。将数值计算结果与实验数据进行了比较，得出了以下几个算例：(I)滑坡引起的波浪；(Ii)溃坝在湿床上的传播；(Iii)波与结构的相互作用。此外，通过几个可视化的例子，使用CPU版本描述了SP物理处理实际情况的能力。(C)2012爱思唯尔有限公司。保留所有权利。
This paper, the second of a two-part series, analyses the efficiency of SPHysics and illustrates its capabilities by means of several test cases. Some intrinsic features of the SPH technique such as the use of link lists and the check for the limits are analysed here in detail. Numerical results are compared to experimental data for several cases studies: (i) Creation of waves by landslides, (ii) Dam-break propagation over wet beds and (iii) Wave-structure interaction. In addition, the capabilities of SPHysics to deal with realistic cases are depicted using the CPU version for several visual examples. (C) 2012 Elsevier Ltd. All rights reserved.
