Data center CFD is often criticized for being too slow. In practice the speed rarely causes an issue since construction and hardware changes are normally planned in advance. However the common approach is to simplify the physics or excessively simplify the geometry resulting inaccurate or, perhaps worse still, uncertainty in whether the results are representative. This discusses two options for increasing productivity while retaining the full physics: Unstructured grid to reduce solution time while retaining the ability to model details where they are important and localized simulations to analyze the impact of small operational changes without a full simulation
