Accelerates and streamlines your product development process

NX Nastran is the industry’s leading FEM (finite element solver), delivering unmatched computational reliability, scalability, accuracy and performance. It comes with powerful solutions for non-linear and linear structural analysis, optimization, thermal analysis, aeroelasticity, rotor dynamics, acoustics and dynamic response analysis integrated into a single, user-friendly interface.

Available as an integrated solver within Simcenter 3D or as a standalone enterprise solution, NX Nastran simplifies modeling processes by presenting a single input/output file format for all solution types.

NX™ Nastran is a standalone solution for the extended enterprise

NX™ Nastran is a premium (CAE) tool that major manufacturers worldwide rely on for their critical engineering computing needs to produce safe, reliable and optimized designs within increasingly shorter design cycle times. For over 40 years, Nastran has been the analysis solution of choice in almost every major industry including aerospace, defense, automotive, shipbuilding, heavy machinery, medical and consumer products – an industry standard for the computer-aided analysis of stress, vibration, structural failure/durability, heat transfer, noise/acoustics and flutter/aeroelasticity.

Typically running on networked server CPUs, NX™ Nastran supports multiple users, multiple sites and/or multiple finite element pre- and post-processing applications, whether supplied by Siemens Digital Industries Software or other CAE solution providers.

Key benefits include:

  • Ideal for customers who need a single flexible, robust and cost-effective finite element solver solution able to support a wide range of product performance simulation processes
  • Proven – Nastran represents over 1,000 man-years of R&D investment by government and industry
  • Provides a high degree of interoperability with a large number of CAE applications and ensures a common simulation backbone across a wide variety of user needs and throughout the entire digital prototyping process
  • Available in two scalable core packages, plus advanced add-on modules that provide solutions for even the most advanced nonlinear structural analysis
