Hi,

I am running a model with air dissocation reactions. I am currently running laminar flow (though at Mach 7.1 it will not be laminar) and am having the issue that when I enable reactions the Courant number drops suddenly. I am able to run the simulations with species transport enabled.

My set-up is as follows:

Steady
Density Based
Axisymmetric
Inlet Diffusion
Laminar-Finite Rate reactions
5 Species gas model
Solution steering - hypersonic (no FMG initialization)

If more details are needed, I can provide them.

I appreciate the help.
