CFD++

CFD++ can efficiently solve compressible flows (at all Mach numbers) and incompressible flows, including both single and multi-species treatment, reacting flows, multiphase flows, steady and unsteady flows, rotating machinery, conjugate heat transfer, porous media, etc.

Various topography-parameter-free models are used to capture turbulent flow features. The nonlinear subset of these models accounts for Reynolds stress anisotropy, streamline curvature and swirl. All these models can be either integrated directly to the wall, or combined with a sophisticated wall-function treatment that models the effects of compressibility, pressure gradient and heat transfer. A single equation LES model and advanced hybrid LES/RANS models are also available.  The latter reduces the cost of traditional large eddy simulation by modeling the near-wall layer and automatically exploiting the advantages of LES in embedded fine-grid regions.
