I found a problem in the use of Premix code. This code gives me good results for a stoichiometry mixture (rich=1.0). forlean and rich mixtures, this code does not finish calculation correctly. My question is as follows: which are the parameters in which I will play to solve this problem?

I think probably the answers lies in the initial condition so lets say if you have converged solution at some quivalence ratio then you can take this converged solution as the intial condition and procedd to the rich case with slight increment of equivalnce ratio. I hope you understand evrything T
