🍪 CFD cookie 3 - How to add numerical tripping/forcing to unsteady turbulent simulations - Part 6

👉 Unsteady RANS with OpenFOAM 😯
Implementing Numerical Tripping/Forcing in Unsteady Turbulent Simulations 🤯

00:00 Introduction
00:51 How to add numerical tripping/forcing | K-Omega SST-SAS with numerical tripping/forcing
04:14 Let's run a few iterations and take a look at the forcing
08:08 Adding turbulent fluctuations and the inlet | Inlet boundary conditions
09:14 Literature review of few numerical tripping/forcing techniques
20:14 Final remarks
This CFD cookie 🍪 is based on OpenFOAM 12, but the general guidelines and standard practices should work with any OpenFOAM version.

🤔 We also address the following question (CFD cookie 1):
Without reference results (experimental, analytical, etc.), how do I know that my turbulent Multiphysics simulations are correct?
