SOLIDWORKS Flow Simulation

Understand the performance of your design before you build a single prototype.

SOLIDWORKS Flow Simulation: Why Choose It?

A product’s success often depends on understanding how air and liquid flow in, through, and around it. With a Computational Fluid Dynamics (CFD) tool integrated into your CAD system, you can create designs like never before. Flow Simulation enables engineers and designers to:

  • Integrated into the SOLIDWORKS 3D CAD interface
  • Looks and behaves like SOLIDWORKS
  • Allows designers and engineers to simultaneously design and simulate – testing a product’s performance in rapid time
  • Provides immediate feedback on the performance of designs as they change
  • Simulates fluid flow and heat transfer on a product design before production

Why choose SOLIDWORKS Flow Simulation?

Tools in Flow Simulation


Computational Fluid Dynamics is a quick and accessible simulation of liquid or gas flow. SOLIDWORKS Flow can generate any number of traditional studies from internal or external domains, time-dependent studies, or compressible/incompressible fluids.


Pictures are the best way to convey complex information. With Flow Simulation, you can illustrate heat transfer, deformation due to heat or pressure, fluid trajectory, or document alternative designs quickly and efficiently.

Thermal Fluid Considerations

Identify thermal hotspots and optimize cooling in your design from the beginning with Flow. The Thermal Fluid capabilities of Flow allow designers to test the impact of things like adding additional fins to a heatsink.

Electronics Thermal Considerations

PCBs and TECs require a unique theory to model. SWX Flow accommodates this and gives the end user specific toolsets to solve complex electronic engineering problems.

Rotating Domains

Thermal issues are usually resolved with the help of a fan. The ability to accurately model these designs’ rotational domain and D-rate is a critical capability of SWX Flow.

Free Surface

Need to solve a problem with both gas and liquid media? The free surface feature allows engineers to mix immiscible fluids. The applications for this type of study are endless.

2D to 3D

The calculations are always performed in 3D by default. It is also possible to run simulations in 2D planes without affecting accuracy when applicable.

Heat Conduction in Solids

There is an option for calculating temperature changes in the solid geometry of the product. Combining convection, conduction, and radiation to transfer heat is possible. Users can include thermal contact resistance in calculations.

SolidWorks Flow Simulation: Identify problems where no fluid exists by calculating pure heat conduction.

HVAC Module: Use semitransparent materials where transparency affects the product’s thermal load to provide accurate solutions.

Electrical Cooling Module: Model-specific electronics device effects, including thermoelectric coolers, heat pipes, and joule heating.

Calculate the effect of rotating or moving devices by simulating moving surfaces or parts.

Free Surface

Simulates flows between immiscible fluids, such as gas-liquid, liquid-liquid, and gas-non-Newtonian liquid.

  • By taking advantage of symmetry, simulation solution times can be reduced.
  • Cartesian symmetry can be applied to the x, y, or z planes.
  • Using sector periodicity, users can calculate a sector of a cylindrical flow.

Flow calculations for subsonic, transonic, and supersonic conditions.

  • It is possible to describe liquid flows as incompressible, compressible, or non-Newtonian (oil, blood, sauce, etc.).
  • It is also possible to determine the location of cavitation in water flows.

Water vapor condensation and relative humidity are calculated when steam is present in a flow.

Boundary Layer Description

A modified approach calculates laminar, turbulent, and transitional boundary layers.

Mixing Flows

Users can perform the flow of any two fluids, whether they are gases, liquids, or non-Newtonian liquids.

Non-Newtonian Fluids

Examine the flow behavior of non-Newtonian liquids, such as oil, blood, sauce, etc.
