How do I remedy a divergence with this message. This is for scramjet combustion in 2D with injectors on both the top and bottom. Is there any way to look up error messages?

I have tried reducing the underelaxation factors but the divergence persists. Any other suggestions? Perhaps in the AMG solver Menu?

It looks like a problem with your boundary conditions, be sure they're compatible with each other and consistent with the physics of what you're trying to simulate,

I think you'd better don't touch anything in the AMG menu, unless you know exactly what you're doing,

It is my opinion, if this could help.

Have a nice day,

Jkl.
