Hi, I'm modelling flow in an IC engine with spark ignition. The Weller model is used for combustion, but when the required time step for combustion is reached, the following warning messages occur, and, looking at the solution(Temperature, Scalar conc, etc.), no combustion takes place.

*** WARNING #042 *** PROCESS NOT FULLY CONVERGED -- EQ.,NIT,RESI: SC1 1 0.88906E-06

*** WARNING #043 *** MINIMUM RESIDUAL AT THE END, RETURNING NON-CONVERGED SOLUTION

Can anyone PLEASE help.
