Igntion happens outside of ignition kernel!
 
1 Attachment(s)
Hello,

I am working with partically prexied turbulent combustion for engine application based on Weller's solver. I added transport equation of fuel mass fraction and some other changes in the library. But I got quite strange results that the ignition occured outside of the ignition kernel (the ignition kernel is located in blue region while regress variable b is reducing at other places also). Then at later time steps DpDt went wrong, and h equation went wrong, and the calulation crashed.


Has anyone met with the similar problem? Thanks for the help!
