is it possible to simulate blast in FDS?

[Saleth-john]

due to CNG leakage fuel is accumulated inside the container. Spark initiating the fire. due to this sudden explosion is happening in the container. is it possible to replicate this scenario in FDS?. I want to measure the maximum pressure inside the container, so I can use the pressure value to structural analysis of the container.

Hello, FDS works with a low Mach number approximation (i.e., no rapid gas compression), so it is not expected to accurately reproduce peak explosion pressures.

Thanks for the info @Vojta-Salek
