    Key differentiators

  • Geometry preparation with SimStudio Tools New

    Quickly modify, simplify, repair and idealize your geometry for higher quality simulation models. SimStudio Tools reads in multiple CAD file formats and allows you to quickly simplify assemblies, eliminate unnecessary detail, perform basic repair, or easily make design changes so you can explore various design ideas faster.

  • CAD connection

    Link your CAD system to Autodesk CFD analysis software to create associative fluid flow and thermal simulations. Autodesk CFD connects to virtually any CAD system, allowing you to create fluid flow and thermal simulations of your designs. If you don’t have a 3D CAD system, use SimStudio tools for geometry creation and model editing and simplification.

  • Automation scripting

    Improve your design process—use the flexible Autodesk CFD Application Programming Interface (API) to automate and customize a wide variety of tasks. Automate repetitive tasks normally performed in the user interface. Create custom tasks and custom results quantities. Output results in customized or specialized formats.

  • High-quality visualization

    Combine analysis results from Autodesk CFD with dedicated visualization tools to create photo-realistic renderings. Gain interoperability with ShowcaseVRED3ds Max, and Maya

  • Design Study Environment

    Use the Design Study Environment for all stages of your design-simulation process. Study design iterations within an intuitive workflow. Drive innovation by providing product teams with data to make informed design decisions. 

  • Intelligent automatic mesh sizing

    Use geometry and solution-based meshing automation. Meshing technology helps you quickly and efficiently prepare geometry for accurate and repeatable result, with automatic mesh sizing, geometry diagnostics, manual control options over local sizes and refinement regions, and solution-based adaptive sizing.

  • Flexible cloud solving options

    Continue working locally while you solve in the cloud. Flexible solving options help you to simulate based on your needs. Test the setup of an analysis, and use your local resources to iterate and optimize your setup. To kick off a longer, more computationally intensive simulation, use the power of the cloud and free up your local resources for other tasks.

    Industry focus

  • Architectural and MEP applications

    Improve occupant comfort, increase operating efficiency, and optimize building design. Access a wide range of CFD features to understand airflow and thermal behavior for architectural and mechanical, electrical and plumbing (MEP) applications. Model radiant heat transfer and solar effects on occupant comfort. 

  • Industrial flow control applications

    Design to reduce pressure drop or optimize flow distribution. Advanced capabilities include the ability to simulate fluid and solid interactions to help reduce valve chatter. Visualize flow fields and model complex cavitation, free surface, and erosion. The intuitive interface works directly with your Inventor or other 3D CAD models. Easily visualize key performance characteristics such as velocity profiles and pressure drop, and compare the results of different designs in a single interface.

  • Thermal management

    Use digital prototyping for your thermal management designs to create one physical prototype for validation. Thermal management solver capabilities in Autodesk CFD include all modes of heat transfer from solid to solid or solid to fluid. The finite element approach solves for the temperature at the surface, allowing easy and accurate mapping to Simulation Mechanical software or another vendor's FEA tool.

    Highlighted features

  • Autodesk CFD 2016 New

    Autodesk CFD 2016 includes new intuitive workflows for geometry and meshing, and expanded physics capabilities.

  • Simplified heat sinks

    Use heat sink materials to simulate the performance of your heat sink components with geometrically simple models. In models containing heat sinks with large aspect ratios (the ratio of fin height to fin spacing), meshing components requires many elements, and a full system analysis can be expensive and time-consuming. The heat sink material significantly reduces mesh counts and improves run times.

  • Free surface

    Dynamically simulate the interface between liquids and gases with free surface modeling capability. Model flow phenomena—such as waves, sloshing, and spilling—that occur in nature as well as in a wide range of engineering applications.
