Autodesk Nastran

Autodesk NastranAutodesk® Nastran® is an industry-recognized, general purpose Finite Element Analysis (FEA) solver used for analyzing linear and nonlinear stress, dynamics, and heat transfer characteristics of structures and mechanical components. The solver works with any Nastran compatible pre- and post-processor and offers real-time results and changes in solution parameters while solving – enabling users to identify and fix issues earlier in simulations. This high-end simulation technology is offered as a value-enhanced package so you can obtain accurate results for complex simulations. Autodesk Nastran is the integrated solving platform for Autodesk mechanical simulation offerings.

Features

  • Normal modes
    Determine the undamped natural mode shapes and frequencies of structures. Designers can explore and resolve problems with noise and vibration.

  • Random vibration fatigue
    The Autodesk® Nastran® random vibration fatigue (or spectral fatigue assessment) feature helps users to simulate vibration shake tests that would have an input. This is particularly applicable to dynamic analyses with random inputs, such as road vibration, wave cycles, wind loads, or engine vibration.

  • Prestress normal modes
    Assess potential problems such as vibration-related operator fatigue or structural fatigue due to structural loading by viewing the normal modes, or natural frequencies, of a structure that might be subject to dynamic loading.

  • Simulation Mechanical, Autodesk Nastran In-CAD integration
    Autodesk Nastran is the finite element analysis (FEA) platform for Autodesk Nastran In-CAD software and Simulation Mechanical software. Use advanced mechanical simulation solving capabilities for Autodesk mechanical simulation products.

  • Autodesk Nastran editor
    The Autodesk Nastran editor gives engineers greater control over their FEA models and results. Features such as advanced editing, context-sensitive input, and dynamic greatly increase productivity and results reliability from the start.

  • Flexible usage
    Autodesk® Nastran® works with multiple pre- and post-processors, allows for multicore deployment, and offers regional and global usage rights for ease of deployment.

  • Linear static
    Determine stress, strain, and deformation resulting from applied static loads and imposed constraints.

  • Steady state heat transfer
    Determine the temperature distribution and heat flow within an object that has time-dependent thermal conditions. This feature includes everything in the steady-state heat transfer capabilities, but also allows for time-dependent loadings and boundary conditions.

  • Pre-stress static
    Analyze structures subjected to initial stress and model the effect of the initial stress state on a structure’s displacements and stresses.

  • Linear and nonlinear buckling
    Run linear or Euler buckling analyses on loaded models to determine the critical buckling load. Nonlinear buckling analysis is also available for loadings and models that do not conform the requirements of linear buckling.

  • Nonlinear static and transient response
    Analyze structures that exhibit nonlinear behavior. Nonlinear effects can be the result of nonlinear material properties, large deformations, and contact-based changes in the boundary conditions.

  • Nonlinear Surface contact
    Nonlinear surface contact capability applies to surfaces defined by both solid and shell elements. Surface contact is ideal for large thin shell fabrications such as ship, aircraft, and automotive structures. Simulate part-to-part interactions of interlocking components, including press-fits, using surface contact.

  • Automated impact analysis, drop test
    View realistic and meaningful projectile impacts and virtual drop test simulations. Automated impact analysis (AIA) introduces the power that automated tools can bring to demanding simulation problems.

  • Advanced material models
    Analyze conventional engineering materials and simulate the latest advanced materials, including composites, shape memory, hyperelastic, viscoelastic, and brittle materials.
