I'm simulating a methane/air combustion in a quadratic chamber using the premixed eddy break up reaction model. The fuel/air ratio is stoichiometric and I'm using the fuel mass fraction ignitor to initiate the combustion. But the ignitor does not "kick inn" unless it's activited on iteration 0 and the ignitor variable value is equal to or less than 0.01. I would like the ignitor to be activited between iteration 10-15. Can anyone please help me?

Use 'time' at which you want the ignitor to be activated instead of iteration in the pulse for the ignitor. It should work.
