31:01 Let's post-process the solution of the wall resolving case | LRE case
35:33 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?
