There is no built-in function for calculating the extinction strain rate in
Cantera. I think gradually increasing the mass flux until you blow out the
flame is the correct approach for finding the extinction strain rate using
Cantera's flame solver. What you should do, though, is use the refined solution
from the lower strain rate case as the initial condition for the next step up
in mass flow rate. As you approach the extinction strain rate, the initial
condition of a stable flame at a lower strain rate is more likely to converge
to the non-extinguished solution (if it exists) than the guessed profiles on a
coarse initial grid. Several of the 1D flame examples show how to restart a
simulation from an existing set of profiles, so that should give you a good
starting point.
(Copied from my response to the Cantera User's Group, which I think is a better
place to address this question)
