超级计算机上的时间序列科学模拟在每个时间步都会生成大量数据。在大数据时代，这些数据变得无法存储，因此强烈要求对这些数据进行同步分析。为了实现这种动态直观的仿真分析，本文展示了一种具有视觉和触觉界面的多模态可视化和转向系统，用于基于 GPU 的实时耦合流固仿真。由于人类触觉的本质需要极快且持续的刷新才能形成真实的感觉，因此利用并行技术将触觉更新速度加快到一毫秒左右。开发了触觉设备的中间层接口，以实现该设备的易用性。此外，还提出了一种触诊模型，允许用户触摸、推动和感知可变形管内的动态流体运动。
Time series scientific simulation on supercomputers generates huge amounts of data at each time step. In the big data era, these data become impossible to be stored anymore, so simultaneous analysis of these data is strongly demanded. In order to realize such an on-the-fly intuitive analysis of simulation, this paper showcases a multimodal visualization and steering system with visual and haptic interfaces for a real-time GPU-based coupled fluid-structure simulation. Since the nature of touching sense of human beings requires extremely fast and continuous refreshing to form authentic feeling, parallel techniques were utilized to speed up haptic updating to around one millisecond. A middle-layer interface for a haptic device was developed to realize the ease of use of this device. Furthermore, a model of palpation was proposed to allow users to touch, push and sense the dynamic fluid motion inside a deformable tube.
