SOLIDWORKS Flow Simulation

SOLIDWORKS Flow Simulation takes the complexity out of computational fluid dynamics.

Flow Simulation gives product engineers access to powerful CFD (computational fluid dynamics) analysis capabilities that help enable them to speed up product innovation. Leveraging the familiar SOLIDWORKS 3D CAD environment, this extensive technology isn’t just about making sure your product works, it’s about understanding how your product will behave in the real world.

Flow Simulation can do for you.

Flow Simulation allow you to simulate liquid and gas flow in real world conditions, run “what if” scenarios and quickly analyse the effects of fluid flow, heat transfer and related forces on immersed or surrounding components. Design variations can be compared to make better decisions, resulting in products with superior performance. Additional valuable modules, HVAC and electronic cooling, offer dedicated fluid flow simulation tools so you can go to the next level for your analysis.

Built to tackle CFD engineering challenges, SOLIDWORKS Flow Simulation enables engineers to take advantage of CAD integration, advanced geometry meshing capabilities, powerful solution convergence and automatic flow regime  determination without sacrificing ease of use or accuracy.

Product engineers and CFD experts alike, armed with the power of SOLIDWORKS Flow Simulation, can predict flow fields, mixing processes and heat transfer and directly determine pressure drop, comfort parameters, fluid forces and fluid structure interaction during design. SOLIDWORKS Flow Simulation enables true concurrent CFD, without the need for advanced CFD expertise.

SOLIDWORKS Flow Simulation software takes the complexity out of flow analysis and enables engineers to easily simulate fluid flow, heat transfer and fluid forces so engineers can investigate the impact of a liquid or gas flow on product performance.

Which version of SOLIDWORKS Simulation is right for me?


SOLIDWORKS Simulation Standard SOLIDWORKS Simulation Professional SOLIDWORKS Simulation Premium
Ease of Use

SOLIDWORKS Simulation is fully embedded in SOLIDWORKS 3D CAD for ease of use and data integrity. Using the same user interface (UI) paradigms as SOLIDWORKS with toolbars, menus, and context-sensitive right-click menus, ensures rapid familiarization. Built-in tutorials and searchable online help aid learning and troubleshooting.

Design Data Reuse

SOLIDWORKS Simulation supports SOLIDWORKS materials and configurations for easy analysis of multiple loads and product configurations.

Static Studies

Solve part and assembly structural analysis problems for stress, strain, displacements, and Factors of Safety (FOS). Problems are limited to static loading, elastic linear materials, and small contact displacements. For the solution to be valid, the resulting deformed shape after loading must exhibit small displacements and rotations.

Premium only: Static studies are extended to incorporate components built up by composites materials. Component setup includes ply orientation and sandwich definition. Results include ply failure index as well as stress and deflections.

Fatigue Studies

Estimate components fatigue life under high-cycle varying loads where the peak stress is below the material yield stress. Cumulative damage theory is used to predict locations and cycles to failure.

Motion Analysis

Use a time-based, rigid body kinematic and dynamic motion tool to calculate the velocities, accelerations, and movements of an assembly under operational loads.

The motion analysis tool calculates component body and connection loads that can be imported into a Static Study.

Professional and Premium only: Use an event-based rigid body kinematic and dynamic motion tool to calculate the velocities, accelerations, and movements of an assembly under operational loads where actions and movements are triggered by the location or movement of components.

The motion analysis tool calculates component body and connection loads that can be imported into a Static Study.

Design Studies

A design study is used to perform wide-ranging “what if” analyses. In a design study, both the parameters of a design (model) and simulation setup (materials, loadings, and fixtures) can be varied to assess the impact of change on the model.

FEA Modelling

SOLIDWORKS Simulation includes solid, shell, and beam modeling using h- and p-adaptive element types with mesh control and failure diagnostics.

A customizable material library is included with simulation data:

  • Parallel computing (multi-core)
  • Batch Run
Professional and Premium only:
  • 2D Simplification
  • Plane Stress
  • Plane Strain
  • Axisymmetric
  • Sub-modeling Simulation

Deformed shape results can be animated and the animation saved.

Overlay Simulation results onto SOLIDWORKS graphics.

SOLIDWORKS Simulation results can be communicated to non-SOLIDWORKS users via eDrawings®, a shareable 3D file format.

Help and Support

In-product tutorials, online help, and knowledge base.

  • Customisable simulation report
  • eDrawings of Simulation results
Thermal Analysis

Solve steady-state and transient part and assembly thermal problems for temperature, temperature gradient, and heat flux.

With the Thermal Analysis completed, you can import temperature loads into a Static Study.

Frequency Studies

Frequency Studies determine a product’s natural modes of vibration which is important for products that experience vibration in their working environment.

Buckling Studies

A possible failure mode for long and slender components is by collapse at a load below material yield stress. The buckling study predicts the components buckling load factor.

Pressure Vessel Studies

Linearised stress, a key for safe pressure design, is calculated in the Pressure Vessel Study.

Topology Studies

Enables you to discover new minimal material design alternatives under linear elastic static loading while still meeting component stiffness requirements.

Linear Dynamic Studies

Builds upon the Frequency Study to calculate the stresses due to forcing vibrations and calculating the effects of dynamic loads, impact or shock loading, for linear elastic materials. Study types are:

  • Modal Time History Analysis
  • Harmonic Analysis
  • Random Vibration Analysis
  • Response Spectrum Analysis
Non-Linear Analysis

Non-Linear Analysis lets you analyze complex material behavior, such as post-yield metals, rubbers, and plastics, as well as to account for large deflections and sliding contact-in components.

Non-Linear Static Study assumes static loads with loads can be sequenced so that the dynamic effects of the varying load do not affect the study. The complex material models in Non-Linear Static Studies can be used to calculate permanent deformation and residual stresses due to excessive loads, as well as predicting performance for components, such as springs and clip fasteners.

Non-Linear Dynamic Study accounts for the effect of real-time varying loads that are included in calculations and results. In addition to solving non-linear static problems, Non-Linear Dynamic Studies can also solve impact problems.
