提出了一种新的光滑粒子流体力学边界处理方法。以前的方法需要使用边界粒子来防止粒子粘在边界上。我们通过用核函数的积分修正SPH的基本方程来解决这个问题。我们的方法能够直接处理三角形网格边界,而不需要边界粒子。我们还展示了如何将我们的方法集成到基于位置的流体框架中。
We propose a new boundary handling method for smoothed particle hydrodynamics (SPH). Previous approaches required the use of boundary particles to prevent particles from sticking to the boundary. We address this issue by correcting the fundamental equations of SPH with the integration of a kernel function. Our approach is able to directly handle triangle mesh boundaries without the need for boundary particles. We also show how our approach can be integrated into a position‐based fluid framework.
