RANS/LES Simulation
Posted: Thu Apr 18, 2019 3:10 pm
Hello,
I am a PhD student in the atmospheric field and I am a débutant in CS.
I am trying to launch a LES simulation (LES Smagorinsky) using my RANS results for the turbulence initialisation but the documentation is limited and not clear. I have used the atmospheric model for my RANS simulations (neutral case) with periodic conditions and the mesh is the same for both cases.
What I have tried so far is to launch a "restart" from my RANS simulation but I keep getting the error "OPTIONS NOT COMPATIBLE WITH TIME DICRETISATION SCHEME" .
I should also add that I would like to use periodic conditions for the LES case. Also, it is not clear if I need to use the cs_user_les_inflow-base.f90 since this is use with the synthetic eddy method initialisation.
I have added the listing and the setup files for my case.
Thanks in advance, any clue is welcome!
