Autodesk Simulation CFD 

provides engineers with comprehensive tools to perform heat transfer and fluid flow analyses.

Autodesk® Simulation CFD software (formerly known as CFdesign®) provides a comprehensive, flexible set of tools for fluid flow simulation and thermal simulation. Autodesk Simulation CFD offers fast, accurate, and innovative analysis capabilities upfront in product development, where decision-making is critical. The Design Study Environment provides performance insight over a range of designs, allowing for greater product innovation and better product performance. Simulation CFD extends Digital Prototyping to electronics cooling, mechanical, AEC, industrial, and consumer product applications.

Autodesk Simulation CFD covers a wide scope of fluid flow and heat transfer scenarios to perform reliable 3D simulations of high-speed turbulent and incompressible flows, along with conduction and convective heat transfer. Simulation CFD comes in three different offerings to meet your specific functionality and budget needs.  Learn which version is best for you in our Product Matrix.

  • Improve design quality with simulation that helps identify potential problems
  • Reduce product development time with digital prototyping
  • Easily simulate 3D models created in Autodesk® Inventor® with tight integration
  • Explore design alternatives earlier in the design process
  • Reduce cost by eliminating costly physical prototypes
  • Simulate in more conditions than are possible or practical with physical prototypes
