Catera with additional transport models
of progress. This bug was reported in the Cantera newsgroup.
The fix consists of replacing
Rc = exp ( mlogA + blogT - Ea / RT)
with
Rc = A * exp (b logT - Ea/RT)
Therefore, the log of A never has to be taken.
Note, this also allows for a zero rate of progress for a reaction.
Consequences:
The permissible range of the rate constant values may be altered.
Numerical roundoff differences will occur, since the order of
operations in key rate constant evalulations has been changed.
Speed of the calculation may be affected. I have no idea which way.
The fix should be considered as provisional. There are different pathways
for fixing this. This is merely the simplest.
