We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Vijay,

Thank you for your reply.

I can confirm your assumptions are correct.

The plotrepresents the total mass within the enclosed domain, and this mass is calculated as a volume integral.

This simulation is transient.

The initial conditions are set with methane (CH4) at 100%, a temperature of 2400K, and a pressure of 39 atm.

The reaction modeled is the one-step thermal decomposition of methane: CH4 ==> 2H2 + C.

Additionally, I have utilized this method for more complex reactions and compared the results with Chemkin, finding them to be similar, without any issues during the simulation runs.
