Nastran® In-CAD

CAD-embedded finite element analysis software.

Autodesk® Nastran® In-CAD software, a general-purpose finite element analysis (FEA) tool for engineers and analysts, offers a range of simulation powered by the Autodesk Nastran solver.

Autodesk® Nastran® In-CAD, a general purpose finite element analysis (FEA) embedded in your CAD system, is powered by the Autodesk® Nastran® solver and offers a wide-range of simulation spanning across multiple analysis types such as linear and nonlinear stress, dynamics, and heat transfer. This single product is available as a network license and serves multiple CAD platforms such as Autodesk® Inventor® and SolidWorks® – providing a consistent user experience and eliminating the need for multiple single-platform simulation technologies. Autodesk Nastran In-CAD delivers high-end simulation technology in a value-enhanced, CAD-embedded workflow so engineers and analysts can make great products.

 * Some features within this product offer partial capability.

 ** Fully coupled fluid/thermal analyses can be performed by CFD alone, where temperature affects convective flow and vice versa (so iterative solving is necessary).

 *** Only availble in Simulation Mechanical Flex.
