This paper proposes a virtual reality (VR)-based in-situ control framework called VR IS-PBVR for simulations in computational fluid dynamics. This framework enables users to observe simulation results in an immersive VR environment while the simulation runs on a supercomputer and interactively adjust simulation conditions based on the visualization results. VR IS-PBVR enables in-situ control without disrupting simulation execution by utilizing compressed visualization particles and file-based communication. Furthermore, by extending the KVS visualization library, which forms the basis of VR IS-PBVR, with OpenXR, we achieved an implementation compatible with general-purpose head-mounted displays. The effectiveness of this framework is demonstrated through an urban wind simulation using OpenFOAM. This example shows that combining immersive VR visualization with interactive steering enables more intuitive understanding and analysis of behavior during simulation execution.

Visualization of large fluid computation results at remote locations by VR, especially using volume rendering, is one of the key challenges in the visualization field. The remote visualization application CS-PBVR is capable of interactive volume rendering of large-scale data in remote locations. In this study, the image generation of CS-PBVR was extended for head-mounted displays to develop a remote VR visualization application, VR-PBVR. We also developed a function that allows manipulation of visualization data by gesture control with both hands in VR space. We applied VR-PBVR to remote volume data and confirmed that it can visualize the data at interactive frame rates.

This study presents the evaluation results of the validity of the visualization map of the ambient dose rate at 1 m above the ground level using an artificial neural network. The dose rate map created using the artificial neural network-based method is found to reproduce ground-based survey results better than conventional methods. Suggested to improve the validity of the airborne radiation survey visualization, applying the color data obtained using a photogrammetry system is a new experience.
