Different results when I use parallel computing

Hi,
I am trying to solve a simple combustion problem with Fluent. However, the result of the mass fraction for specific gas when the Solver Processes parameter is 1 is significantly different from the case when I change it to 16. Do you have any idea where this difference is coming from and how I can fix it? Thanks |

Any convergence or stability issues?

Yes, I understand. It seems I didn't describe the problem very well.
I am just changing the number of the processors to 16, and as a result, the mass fraction at the end of the time step in my goal location is significantly different from the case I have just 1 processor! Thanks |

No issue at all. It's working very well in both cases. However, the results are different.
