Computational Fluid Dynamics (CFD) Software Integrated With SOLIDWORKS

SOLIDWORKS Flow Simulation gives you powerful fluid flow analysis tools directly in your 3D CAD interface and offers easy, automated test setup and quick feedback. With integrated CFD, you can accurately predict product performance as it relates to fluid flow, airflow and aerodynamics, as well as heat transfer and cooling.

Take the complexity out of CFD. This easy-to-use software was built with product designers like you in mind, helping you go from concept to product quickly, designing and testing at the same time.

Frequently Asked Questions

Is a SOLIDWORKS license needed to use Flow Simulation?
Yes, a SOLIDWORKS license is needed, but it can be any of any type – Standard, Professional or Premium.
How is SOLIDWORKS Flow Simulation licensed?
SOLIDWORKS Flow Simulation is available as both a perpetual license (with subscription) or as a term license. It can be activated on a particular machine or shared as part of a network license pool (additional costs apply).
Are there any special hardware requirements for Flow Simulation?
No, the hardware requirements are the same as those for SOLIDWORKS.
What kind of fluid calculations does SOLIDWORKS Flow Simulation perform?
Flow Simulation solves the Navier-Stokes equations (RANS and FANS) to calculate velocity fields, pressure, and other fluid parameters.
Can SOLIDWORKS Flow Simulation calculate heat transfer?
Yes, conduction, convection, and radiation are all directly calculated based on fluid flow, material properties, and other input conditions.
Yes, Flow Simulation can simulate complex models with both passive and forced air cooling. The optional Electronics Cooling add-on module supports further details such as PCB layer properties and 2R component model for chips.
What types of fluids can be simulated?
Available fluid models include ideal gas, real gas, liquids, compressible liquids, and non-Newtonian liquids.
Does SOLIDWORKS Flow Simulation support moving geometry?
Most types of mechanical and free body motion are not supported. Rotating components, however, like fans and impellers can be simulated with the Sliding Mesh capability.
