Hi,

Urgently i need to learn how to set up DES and DDES turbulence models for my own openFOAM case. Looked for tutorials cases as well, but could not find any.

really really appreciate if someone can guide me how to learn this

Thank you,

There are a few that I know of... at least for openfoam+. Here's one for a cube of sorts: tutorial. And here's one for a hill of sorts: tutorial.

Those tutorials are simply supplied with OpenFOAM so I didn't set them up. Given that IDDES is simply improved DDES though (if I remember correctly) it could be worth trying one of the tutorials with DDES and seeing what happens to start... someone else with more DDES experience can likely give better advice in that regard.
