‌Fluent DPM模型中的高分辨率跟踪选项详解‌

找不到中文资料，顺手写一点能找到的资料

一句话总结：效果显著，但需要的算力很大，适合基于实验的模拟复现

“Main menu containing settings that control the High-Res Tracking scheme. When the High-Res Tracking option is enabled (default), the computational cells are decomposed into tetrahedrons (subtets) and the particles tracked through the subtets. This option provides a more robust tracking algorithm and improved variable interpolation. If High-Res Tracking is not enabled, particles are tracked through the computational cells directly. Flow variables that appear in particle equations either use cell-center values or a truncated Taylor series approximation for interpolation to the particle position.”

主菜单包含控制高分辨率跟踪方案的设置。启用 "高分辨率跟踪 "选项（默认）后，计算单元被分解为四面体（子集），粒子通过子集进行跟踪。该选项提供了更稳健的跟踪算法和更好的变量插值。如果未启用 "高分辨率跟踪"，则直接通过计算单元跟踪粒子。粒子方程中出现的流动变量要么使用单元中心值，要么使用截断泰勒级数近似值对粒子位置进行插值。
