Partially premixed model: Divergence
 
Hello,
I am trying to do combustion analysis of a gasoline engine at octane lower than regular gasoline (which i assume as 90). The cases with octane numbers of 87 and 85 diverged giving: "Divergence detected in AMG solver: pressure correction". All the parameters were kept same from the 90 octane case which ran smoothly and gave me predicted results. Can anyone address this issue.
