The Premier FEA Solver


An industry standard for over 40 years, Nastran is a finite element (FE) solver for stress, vibration, buckling, structural failure, heat transfer, acoustics and aeroelasticity analyses. Manufacturers as well as engineering suppliers in aerospace, automotive, electronics, heavy machinery, medical device, and other industries rely on NX Nastran software for their critical engineering computing needs so they can produce safe, reliable and optimized designs within increasingly shorter design cycles. NX Nastran delivers:

  • A broad set of technical solutions and advanced applications all from a single solver.
  • Computational performance, accuracy and scalability for small to very large models with hundreds of millions DOFs
  • The ability to integrate easily with other leading CAE tools developed by Siemens as well as other CAE vendors

Computational Performance and Numerical Accurancy

Finite element analysis models have consistently grown in size as engineers continue to tackle more complex problems through the increase in computing capacity. Today, complex models with tens of millions of node points and elements are common. Performance is what makes NX Nastran the solution of choice for users who need to solve today’s increasingly large problems.

Ease of Modelling and Engineering Workflow

To simplify the modeling process, NX Nastran integrates with Siemens DISW own leading pre/post processors – Simcenter 3D and Femap.  Engineers can also easily create NX Nastran models through a number of available third-party FEA preprocessors that support NX Nastran.   But NX Nastran itself also includes unique features that enable engineers to quickly connect complex components together and speed process time.

Flexibility and Openness

NX Nastran gives engineers the flexibility to add their own custom analysis modules. Siemens DISW also works with solution partners who wish to integrate their products with NX Nastran.
