Hello everybody,
I am try to simulate a natural gas flame using the unsteady flamelet model. On the steady flamelet model it works fine. The first model I made works with the unsteady flamelet model. Then I draw a new grid an set up a case based on the first one (same flamelet, PDF, boundary conditions, turbulence model…). There I can’t choose the unsteady flamelet model.
The flow field is conjugated, the solver stands on steady.
Any Ideas?

Hi
After getting the steady flamelet I am not able to initialize unstaedy flamelet for partially...premixed.. it shows the mixture fraction error. I am trying to ignite the nheptane/N2/Ar/O2: 0.562/58/30/10.3 , by mole fraction
I am getting only the steady flamelet

Please help me how to reduce or set the mixture so to avoid this error.
I am trying by putting the scaler to all possible values between 1 to 0 the error is not disappearing

I am in bit great need ... Pl help
