1. A method of computational fluid dynamics modeling a bounded domain, the method comprising: dividing the bounded domain into at least one viscous region and at least one inviscid region; performing viscous domain solve for the at least one viscous region using at least one turbulence model; performing inviscid domain solve for the at least one inviscid region using a set of inviscid equations; and providing results of the viscous domain solve and the inviscid domain solve as a model of the bounded domain.
