1. A method comprising: performing computational fluid dynamics modeling of a bounded domain, the bounded domain comprising a data center, the performing comprising: processing the bounded domain to automatically locate and separate within the bounded domain at least one viscous region and at least one inviscid region of the bounded domain using a turbulence characteristic threshold criterion to divide the bounded domain into the at least one viscous region and the at least one inviscid region; separately evaluating the at least one viscous region and the at least one inviscid region by: performing viscous domain solve for the at least one viscous region within the bounded domain using at least one turbulence model; performing inviscid domain solve for the at least one inviscid region within the bounded domain using a set of inviscid equations; and providing results of the viscous domain solve and the inviscid domain solve as an internal model of the bounded domain.
