Hi, is here anybody who did a simulation of diffusion flames using laminar flamelet model together with RSM for turbulence? I'm having quite a hard time trying to avoid divergence early from the switchover to RSM from any other turbulence models.

Thanks George

i think i have done it long ago, i don't rem much but i din't get the divergence

Thanks for your input, I will definitely give it another try, perhaps in a simpler geometry to have a better chance.

actually i should have written that as i rem that case started to diverge but soon i realised and set very low URFs for various things like enegery and momentum keepign this changing slowly and i got the convergence, so i honestly advise you to use lower urf (i don't know why it diverges for higher urfs but it does).

best of luck
