为了捕捉稳定、真实的流体表面微观特征，本文提出了一种基于隐式不可压缩SPH（平滑粒子流体动力学）的表面张力和粘附方法。给出了稳定、快速的张力模型，可以解决不考虑粘附力的问题。表面张力考虑了分子内聚力和表面最小化，并添加了粘附力以显示表面的微观特征。为了稳定有效地模拟表面张力和粘附力，将表面张力和粘附力模型集成到隐式不可压缩 SPH 方法中。实验结果表明，与之前的方法相比，该方法能够更好地模拟多种场景下的地表特征，同时保证稳定性和效率。
In order to capture stable and realistic microscopic features of fluid surface, a surface tension and adhesion method based on implicit incompressible SPH (smoothed particle hydrodynamics) is presented in this paper. It gives a steady and fast tension model and can solve the problem of not considering adhesion. Molecular cohesion and surface minimization are considered for surface tension, and adhesion is added to show the microscopic characteristics of the surface. To simulate surface tension and adhesion stably and efficiently, the surface tension and adhesion model is integrated to an implicit incompressible SPH method. The experimental results show that the method can better simulate surface features in a variety of scenarios compared with previous methods and meanwhile ensure stability and efficiency.
