Add to_cantera_kinetics for SurfaceArrhenius and StickingCoefficient kinetics classes

Open sevyharris opened this issue 1 year ago • 5 comments

Motivation or Problem

We want to be able to convert from RMG surface reaction kinetics to Cantera kinetics for simulation purposes. It's faster to do this in memory than through loading a whole file.

Description of Changes

This PR implements the to_cantera_kinetics functions so RMG reaction objects can be easily converted to Cantera objects

Testing

COMING SOON: a Jupyter notebook to help compare an example RMG/Cantera surface mechanism

Reviewer Tips

COMING SOON: a Jupyter notebook to help compare an example RMG/Cantera surface mechanism

This looks helpful, and indeed necessary for https://github.com/ReactionMechanismGenerator/RMG-Py/pull/2321.

What would be some suitable unit tests? Can we go in both directions (to and from Cantera) allowing round-trip testing? Else I guess a few specific examples of different rate types and stoichiometries to check the units?
