Regarding the solver

[CLAUDIO]

Hi everyone,

I hope you are doing OK. I am working with Cantera, using 1D flames and reactor networks. However, I still am a bit doubtful about the solver. When advancing time in simulations, is the solver explicit or implicit? Do I get a choice in this? Can I apply under-relaxation factors to species and temperature?

I would be really gratefull if you could point me in the right direction, since some of my simulations have been diverging and I think under-relaxation could be key to avoid it.

Best regards

Please refer to some newly added documentation to find out about the solver used for 1D: https://cantera.org/stable/reference/onedim/nonlinear-solver.html, as well as the solver docstrings themselves. The solver used for reactor networks is based on Sundials' CVODES/IDAS: https://cantera.org/stable/reference/reactors/index.html#reactor-networks. Beyond, searching posts in this user group should yield some posts that may be relevant to your question.

TLDR: under-relaxation is not among the options available.
