Description (last modified by Gary J. Ferland)

the attached very high density model finds non-physical abundances for . We include lamda cooling for these molecules, which derives the temperature to unphysically low values.

slow/grid_extreme faults, but the attached sim does so quickly

The sim finishes fine if *both* of these reactions are killed:

newreact("O2,Cl+=>Cl,O2+",hmrate,0.00000000046,0,0); /* UMIST */
newreact("Si,O2+=>O2,Si+",hmrate,1.6e-9,0,0); /* UMIST */

Stancil's guess about reverse reactions did not seem to help.
