I'm very interested in this information.
I work in this space for MEP Building performance engineering.
We worked with some clients doing CFD analysis for simulating heating / cooling for data centers, mining operations, and military installations.

I personally do not have the experience for CFD analysis but it is compelling work.
By building models in Revit we can fast track the simulation aspects in CFD tools like Autodesk CFD. This is not cheap software simulation but it is important for understanding stratification and where trouble areas might be.
Our Energy engineers spend a lot of time on enhanced commissioning to see what the actuals are vs. what the predicted outcomes are. Usually field adjustments are always needed.
