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.

I just noticed that you had already mentioned that the walls are adibatic. Is this choice accurate or should it have a non adiabatic BC ?

What is the change in pressure and temperature within the domain once the reaction starts. Could you share snippets of temp and pressure contours for CH4, H2 and CO2 driver cases (at points before and after the mass imbalance appears).
