跟踪特征并探索其时间动态可以帮助科学家识别模拟中有趣的时间间隔，并作为对时间现象进行定量分析的基础。在本文中，我们开发了一种跟踪等值面子集的新方法，例如模拟火焰中的燃烧区域，这些区域被定义为温度等值面上的高燃料消耗区域。跟踪这些区域随着时间的推移合并和分裂可以为了解湍流对燃烧过程的影响提供重要的见解。然而，温度等值面的复杂性质及其快速运动使得这种分析特别具有挑战性。
Tracking features and exploring their temporal dynamics can aid scientists in identifying interesting time intervals in a simulation and serve as basis for performing quantitative analyses of temporal phenomena. In this paper, we develop a novel approach for tracking subsets of isosurfaces, such as burning regions in simulated flames, which are defined as areas of high fuel consumption on a temperature isosurface. Tracking such regions as they merge and split over time can provide important insights into the impact of turbulence on the combustion process. However, the convoluted nature of the temperature isosurface and its rapid movement make this analysis particularly challenging.
