This PR looks good to me. The bigger question is if it makes sense to use a library value when you scale across the periodic table since your estimate of the barrier would not be great anyway. At least this adjustment makes sure that the barrier is somewhat reasonable. Let me know when you have tested this on a Pt mechanism and I'll leave an approving review. |
Thank you @bjkreitz for reviewing this! I have now done the test for Pt and it looks good-- doesn't change any barrier heights. I will keep that in mind about scaling from a library. |

The changes look good to me. I tested this feature by generating a mechanism for Pt(111) and Ni(111) with the Deutschmann library. Nothing is adjusted for the Pt(111) system, but a few activation barriers are raised to match the endothermicity of the reaction when scaling to Ni(111). I approve the changes. Thanks Sevy!

Motivation or Problem
If you include a library for a surface mechanism that uses linear scaling, this can cause some reaction barriers to be below the endothermicity of the reaction. This PR fixes the barrier heights for library reactions that have been scaled across metals.
See #2726 for more details of the issue.
Description of Changes
This PR adds a call to fix_barrier_height() if the library reaction is a surface reaction with any species thermo that has been scaled across metals.
Testing
I have tested with this CPOX on Rh RMG input.txt and confirmed that it raises the barrier for the O2 dissociative adsorption reaction taken from the Surface/CPOX_Pt/Deutschmann2006_adjusted library:
vs, the original:
I have not yet tested that it doesn't scale the same input file if you try to generate a Pt mechanism, but I plan to.have now confirmed it doesn't bother fixing barriers for regular Pt mechanism.
