View source for Auto-ignition CH 4/Air flame with scheme GRI12

== '''Objectives''' ==

The AutoIgnition_GRI12 test case shows an example of CH4/Air auto-ignition using the GRI12 mechanism.

== '''Key parameters''' ==

We are at atmospheric pressure, and the fuel is injected in its gaseous form (no evaporation model). We are using the stochastic configuration and we follow only one premixed CH4/Air fluid particule for ignition. 


Characteristics of the premixed particule (Phi = 1) :
   listInlets.push_back(new MultipleInlet(
                /*Temperature*/ 1000,
                /*Pressure*/ 1E+05,
                /*Mass flow rate*/ 0.001,
                /*Xk*/ "",
                /*Yk*/ "CH4:0.0550661, O2:0.220264, N2:0.72466990",
                /*Evaporation model*/ false,
                /*Droplet diameter*/ 0.0,
                /*Evaporation time*/ 0.0,
                /*Liquid density*/ 0.0,
                /*Evaporation latent heat*/ 0.0));

Characteristics of the burned gases inlet : (This inlet should always be present as it defines mixing time, time step and the iteration number. The mass flow rate is put to 0 in order not to consider this inlet.
