Explosion Model
 

Has anyone had success using the new explosion model in CFX 4.3? I am trying to simulate NOx production in an internal combustion engine fired with natural gas. We recently migrated from 4.2 to 4.3 and had made several modifications with User Fortran to incorporate our own version of an explosion model. However, in 4.3 I am unable to get beyond the spark stage! I have tried several variations of all the parameters (ignition length, flammability limits, ignition duration, etc.).

I have read the user manual and even obtained some extra documentation from AEA but I still have questions. Can anyone help me?
