Abstract

Fluid dynamics simulation is often repeated under varying conditions. This leads to a generation of large amounts of results, which are difficult to compare. To compare results under different conditions, it is effective to overlap the streamlines generated from each condition in a single three-dimensional space. Streamline is a curved line, which represents a wind flow. This paper presents a technique to automatically select and visualize important streamlines that are suitable for the comparison of the simulation results. Additionally, we present an implementation to observe the flow fields in virtual reality spaces.

摘要

流体动力学模拟通常在不同条件下重复进行。这会产生大量难以比较的结果。为了比较不同条件下的结果，在单个三维空间中重叠从每个条件生成的流线是有效的。流线是一条曲线，代表风流。本文提出了一种自动选择并可视化适合模拟结果比较的重要流线的技术。此外，我们还展示了一种在虚拟现实空间中观察流场的实现方法。
