为了缩短汽车行业的设计周期和降低开发成本，仿真工具被广泛用于整个车辆开发过程的分析和测试。有限点集方法（FPM）已被应用于数值预测流体运动的车辆行驶通过水体。FPM是一种基于广义有限差分公式的纯无网格方法。它使用最小二乘算子对零维数值点云上的流场进行离散，因此特别适用于有自由表面的流动。FPM已经成功地应用于各种工业问题，显着的瞬态表面变形，包括气囊展开，玻璃形成，填充和晃动过程。在雨季或越野驾驶很重要的市场中，确保车辆在水体中行驶而不被损坏的能力是必要的。使用FPM作为水旅行的模拟工具的过程的开发分两个阶段进行：在一盆水上的操作进气口的两相水/空气模拟，以及使用移动车辆的单相模拟。
In order to shorten design cycles and reduce the cost of development in the automotive industry, simulation tools are widely used for analysis and testing throughout the vehicle development process. The Finite Pointset Method (FPM) has been applied to predict numerically the fluid motion as a vehicle travels through a body of water. FPM is a purely meshfree approach based on a generalized finite difference formulation. It discretises the flow field over a cloud of zero-dimensional, numerical points using least squares operators, and is therefore particularly suitable for flows with free surfaces. FPM has already successfully been applied to various industrial problems with significant transient surface deformation, including airbag deployment, glass formation, filling and sloshing processes. Ensuring the ability of a vehicle to travel through a body of water without being damaged is necessary in markets where monsoon rain occurs or where off-road driving is important. The development of the process to use FPM as a simulation tool for water travel was carried out in two stages: a two-phase water/air simulation of an operating air intake over a basin of water, and a single phase simulation with a moving vehicle.
