[petsc-users] How do I know it is steady state?

[Zou (Non-US), Ling]

Hi All,

>From physics point of view, I know my simulation converges if nothing
changes any more.

I wonder how normally you do to detect if your simulation reaches steady
state from numerical point of view.
Is it a good practice to use SNES convergence as a criterion, i.e.,
SNES converges and it takes 0 iteration(s)

Thanks,

Ling
