I present the research result of "Remote Interactive In-Situ Visualization using Particle Data for Volume Visualization" supported by the Joint Usage/Research Center for Interdisciplinary Large-scale Information Infrastructures (JHPCN), 2017. With the increase of simulation scale, the conventional visualization process involving data transfer to the pre-post node requires a huge processing cost. To enable real-time visualization and analysis of large-scale simulations, an interactive In-Situ visualization system using particle data for visualization is optimized for the latest SIMD platforms such as XeonPhi, and FX100. Using this system, interactive visualization at runtime is enabled for batch processing simulations.

The simulation for dissipation of radioactive substances attract high social interest, and it is required to satisfy both the rapidity and the accuracy. To perform a real-time simulation with high resolution mesh for the scale of human living area such as alleyways and buildings, it is required to develop simulation schemes which can fully utilize high computational performance. In this study, we introduced a nudging-based data assimilation method into the lattice Boltzmann method (LBM), so that we can performe plume dissipation simulations for urban area.
