use fvOption to set high temperature zone
 

Hello dear Foamers,

I use fvOption to set a high temperature for ignition, the solver read it but the results (runing at time 1e-6s) show that there is no such high temperautre zone.
Could you please tell me why this happen?

The fvOption file and the running process are shown below.

Thanks in advance.
