Hi all,

I am a brand new user of Converge Scienceand I am really happy that it is a specific CONVERGE section here in CFD-Online.
I just have some questions regarding a simulation that I have to run:
I would to evaluate the flame speed of a spherical flame inside a box, I decided to use the GLevelSet Equation to represent it.
Unfortunately I am not able to let the flame growing inside the domain and, even though I flag the G_EQN_TRANSPORT and G_EQN_PROGRESS inside Post_variable_section->Species/Passive, I do not succeed on having the flame as output.
I use Converge v 3.0.9 on Windows.

Thank you so much in advance.

Best regards
Francesco

Hello Francesco,


The case setup you have attached has the following issues,
1) A mechanism file is missing. As you are using G-Equation with CEQ, the mech.dat needs to include the equilibrium species and no reactions.
2) The species in mech.dat need to be available in therm.dat
3) Please source G Transport as a source of ignition


Thanks,
Nitesh
