Autodesk® Simulation software, part of the Autodesk® solution for Digital Prototyping, provides a range of mechanical simulation tools to help designers, engineers, and analysts make decisions earlier in the engineering design process. With these tools, you can predict the real‐world performance of your product, helping to save the time and money required to build multiple physical prototypes.

Autodesk® Simulation software lets you start with mainstream tools and then expand your toolkit to include more advanced simulation such as computational fluid dynamics (CFD)—without the need to learn new workflows.

With Autodesk® Simulation Multiphysics software, you can use CFD tools to perform heat transfer and fluid flow simulations in order to study the thermal characteristics of designs and simulate accurate, detailed fluid flow behavior.

The fluid flow simulation tools help you predict flow patterns in multiple, independent fluids by calculating velocity and pressure that occurs within incompressible, viscous flows—including the simultaneous prediction of laminar and turbulent flow and combined fluid/thermal effects, such as natural convection (buoyancy) and forced convection. These tools can simulate the flow of incompressible fluids around obstacles, such as airfoils, or within hollow places, such as lid-driven cavities.

Setup of CFD simulations is made easier through the use of standard engineering terminology, workflow guidance, and user-friendly tools and wizards that automate the transfer of simulation results between multiple analyses—letting you focus on product performance, not advanced numerical or simulation methods.

Support for multi-CAD environments and finite element modeling tools help manufacturers study initial design intent and accurately predict product performance. Autodesk® Simulation software supports direct data exchange with most CAD software tools, Autodesk® Moldflow® plastic injection molding simulation tools, and Autodesk® Vault data management software. Autodesk® Simulation software allows you to validate and optimize designs before manufacturing—increasing efficiency, minimizing reliance on physical prototypes, reducing costs, and decreasing errors.
