Autodesk® Nastran® In-CAD




CAD-embedded finite element analysis software

Autodesk® Nastran® In-CAD, a CAD-embedded general purpose finite element analysis (FEA) tool powered by the Autodesk® Nastran® solver, offers a wide-range of simulation spanning across multiple analysis types. It delivers high-end simulation in a CAD-embedded workflow so engineers and analysts can make great products.


    • Surface contact :
      Accurately simulate and model parts with different kinds of contact, such as sliding, friction, and welding.
    • Linear buckling :
      Analyze structures, such as columns and beams, for catastrophic failure under certain loading conditions.
    • Automated drop test :
      Automate projectile impact and virtual drop tests for phones, laptops, and many other products.
    • Frame Generator idealization :
      Select which structural members will be automatically idealized as beams.
    • Impact analysis :
      Solve impact events and drop testing of all types of nonlinearities at the same time.
    • Frequency response :
      Determine the structural harmonic response, based on frequency-dependent loads.
    • Bolt and connection :
      Easily mesh models, and run the solver for bolts and connections analyses.
    • Static fatigue :
      Determine the durability of structures under repeated loading, including low- and high-cycle fatigue.
    • Automatic midplane mesher :
      Idealize thin solid models as a shell.
    • Heat transfer :
      Avoid assembly failure due to high thermal stress.
