Recently, I am working on non-premixed combustion in porous media. However, compared with the experimental results, the flame seems too short and the combustion process is quite stiff.

Because of getting divergent results in former cases, I use Stiff Chemistry and Coupled solver to take a special care of this laminar finite rate model. I doubt if it is the Stiff Chemistry Solver that causes the problem.

Is there someone who once had the same problem?
