In the field of scientific simulation, the use of free software, which usually opens its source code, has been attracting attention recently. Free software is an effective way to reduce software-licensing costs. The Fire Dynamics Simulator (FDS), which is a large-eddy simulation (LES) code for low-speed flows including fires, is a successful open source project for scientific simulation. To perform fire experiments safely, it is important to predict the fire dynamics before the experiments. In this study, a bonfire test of high-pressure hydrogen-storage tanks is calculated with FDS. It was found that the temperature of the thermal-pressure relief valve at the edges of the tank rose when a wall and an entrance were placed properly around the tank.
