本应用论文提出了一种基于拓扑数据分析的新颖框架，用于相对于参考采集对集成中的粘性手指模拟运行进行自动评估和排序。给定时间步长中的各个手指与到注入点的距离场中的关键点对相关联，形成持久图。介绍了基于最佳传输的不同指标，用于比较此特定应用案例中的时变持久性图。我们评估通过这些指标获得的排名的相关性，既通过轻量级网络可视化界面进行定性评估，又通过研究与专家建议的参考排名的偏差进行定量评估。大量的实验表明，与传统的替代方案相比，我们的方法在数量上具有优势。我们的网络界面允许专家方便地探索生成的排名。我们展示了一个完整的粘性指法案例研究，展示了我们的方法在多孔介质流体流动背景下的实用性，其中我们的框架可用于自动丢弃整体中与物理不相关的模拟运行，并对最合理的模拟运行进行排名。我们记录了现场实施，以减轻参数研究背景下出现的 I/O 和性能限制。
This application paper presents a novel framework based on topological data analysis for the automatic evaluation and ranking of viscous finger simulation runs in an ensemble with respect to a reference acquisition. Individual fingers in a given time-step are associated with critical point pairs in the distance field to the injection point, forming persistence diagrams. Different metrics, based on optimal transport, for comparing time-varying persistence diagrams in this specific applicative case are introduced. We evaluate the relevance of the rankings obtained with these metrics, both qualitatively thanks to a lightweight web visual interface, and quantitatively by studying the deviation from a reference ranking suggested by experts. Extensive experiments show the quantitative superiority of our approach compared to traditional alternatives. Our web interface allows experts to conveniently explore the produced rankings. We show a complete viscous fingering case study demonstrating the utility of our approach in the context of porous media fluid flow, where our framework can be used to automatically discard physically-irrelevant simulation runs from the ensemble and rank the most plausible ones. We document an in-situ implementation to lighten I/O and performance constraints arising in the context of parametric studies.
