Hi Atish,

I contacted the developer regarding your question. He said "For the sudden explosion problem, if the fluid speed is not high, it is better to use an incompressible solver such as ICFD. Currently, there is no species transport model in dual-CESE solver, but in the old CESE solver, there is combustion/chemical-reaction capabilities implemented. As for the difference between CESE results and Fluent, I couldn't comment since I don't know how his dual-CESE model set up."

I hope this informations is helpful.

Thanks,

Pedram
