Hello FOAMers!
I am working on a shock-wave case and I'd like to use the rhoCentralFoam solver. I understand that this solver is transient but my question is: Can it be used in LES or in URANS? Where can I find more info? Thank you in advance! |

Dear Calmly,
You can use rhoCentralFoam for LES or DES simulations. You do not need to do any changes for the solver but you have to change your turbulenceProperties file in order to make a LES analysis. Oguz |

In OF V5.x can k-omega SST DES be implemented with no changes except in the turbulence properties file?

Thanks a ton Fatih! Was very helpful.
Have u implemented DES model in Openfoam? |
