IC engine Spray-EBU combustion model problems
 
I set up an IC engine combustion chamber model with a C12H26-L nozzel. The Spray works well. When I config the chemical-reaction model,Star-cd automatically creates scalars C12H26,mix,O2,N2,RAC-1,Rac-2,Rac-3 etc. The problem is Mix,Rac-1-2-3 do not appear in the combustion chamber,so the ignition do not run in the 50th step. I confirm that I have set these scalars as "Post",But I dont know why they do not come out in the chamber.

Could anybody help me? thanks a lot.
