Cantera+OF, new problem
 

Now a new problem occured. In the HM1 combustion exp, velocity is that: Ujet=118m/s, Uco=40m/s. I made a mistake, I set the velocity of fuel 118m/s, and the velocity of air 40m/s, but now, when I set the velocity of fuel 40m/s, and the velocity od air 40m/s, the computation crashed when time =8. When I go back, everything is OK This is confusing.
