I am simulating the combustion process of GDI engine.The spray is initiated through the inbult spray panel.Here I am using local sources combustion modeling with premixed mixture.The rate model is CHKI with standard options. The ignition cell is also located.The question is : I am not getting the mixture ignited and hence the case runs as if it were a cold case analysis. Is there some other parameters like activation energy ignition temperature? Is there any other combustion model inbuilt in starCD which can be suitably adopted?

Thanks for responding

Use "transport" instead of "Internal" for the scalars.

Can you send me the combustion model to my email address.
