HCN hooks could also be used in parallel to CO_YIELD in the single-step reaction. I think the fact that HCN definition is a bit tricky is biasing FSE evaluations to...

Yes, yield is ventilation dependent. But so is CO. At least we should make it easier for engineers to include HCN. FED algorithm should recognize it straight away. Now, I...

I think the use of CO_YIELD, and HCN_YIELD in the future, is quite unconnected from the actual fuel chemistry. This is the engineering method to model toxicity. Most cases I...

OK, I originally was thinking the stoichiometry and N mass balance would not matter at all, like what Randy was saying, but I also see the point of requiring the...

Great job Jason! I will see if we can generate a verification test. The current FED verification tests use initialized individual tracked species or SMIXes. Can we initialize a constant...

The post-combustion yields are now used in FED_CO_HCN test. Not yet in Verification guide. Want to see how everything else runs.

Expected data can be produced with this script from the _devc file containing gas concentrations [fed_co_hcn.zip](https://github.com/firemodels/fds/files/5371607/fed_co_hcn.zip)

Jason, I am thinking of test cases for the two-step reaction now. Do we have a way to specify/measure the equivalence ratio of a given volume where we initialize temperature,...

Working on it. Few issues on the way: - Inside solid, we solve RHO_ZZ, and it would be the easiest output. I think we do not have a name for...

Would it be clearer to use 'SOLID DENSITY' in all outputs, whenever referring to solid (a MATL or all MATLs)? DENSITY alone could always mean gas.
