Hello,
i am trying to simulate a combustable jet, but i cant get the pressure field to convergence. the minimum pressure seems to just keep reducing until the solution crashes. I have put up my pressure boundary conditions. |

You have specified Pressure to be constant at both inlet and Outlet..
Try to Check your mesh for non-orthogonality and skewness. |

I Have tried to change the pressure boundary conditions but no luck, I was wondering for combustion in the thermogas file for the species model in nmoles do i specify 1 or the number of moles in the reaction? as I have specified 1 as was in the tutorials however i was unsure about why.

This is what I have for the species model as running
