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.

1)

The velocity at the very inlet is 0 m/s, which already seems very odd. Especially since the mass flow rate is 1.8551e-3 kg/s at the inlet.

 

2)

I did not add anything specific to ignite it (did not patch it or anything). I filled in the model, BCs, initialised it and then I ran the simulations.

 

3)

I have tried both the Heat Flux thermal condition and the Mixed thermal condition. I did not adjust any values in here, except from changing the material from aluminum to steel.

 

4)

I have tried running it for longer but the results did not seem to change.
