Introducing a revolutionary new concept in flow analysis - COSMOS/Flow. Unlike other computational fluid dynamics programs, COSMOS/Flow combines a high level of functionality and accuracy with ease-of-use. Designed with the non-specialist in mind, COSMOS/Flow is perfect for the engineer who needs flow analysis, but is not an expert in the field of fluid simulation.

COSMOS/Flow is a general- purpose computational fluid dynamics (CFD) code that can model the analysis of gases and liquids through a wide range of Reynolds numbers. You'll find it easy to factor forced, natural, mixed and radiative heat transfer effects into the analysis. The COSMOS/Flow software includes a fluid property database with common fluids. Users can add, delete and edit this database. A solid property database is also available which again can be added to and edited by the user.

COSMOS/Flow can be used in a diverse array of applications and has been designed to be extremely flexible. Whether you are developing an automobile, the wing of an airplane, or an exhaust valve, using COSMOS/Flow in the product development cycle can help you build a better product in less time.

COSMOS/Flow can simulate these parameters and more:

COSMOS/Flow is embedded in COSMOS/DesignSTAR and can also be purchased as an add-on to COSMOS/Works.
