NX Nastran advantage

The premier FEA solver
An industry standard for over 40 years, Nastran is a finite element solver for stress, vibration, 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 NXâ„¢ Nastran® software for their critical engineering computing needs so they can produce safe, reliable and optimized designs within increasingly shorter design cycles.

Develop products faster
Simulation with NX Nastran helps engineers to find problems with product designs earlier before conducting any costly physical tests. With NX Nastran, engineers can be confident their design will work when the first physical prototype is tested.

Increase product quality
NX Nastran enables engineers and designers to rapidly evaluate many more design concepts than can be accomplished with physical prototypes. Simulation allows engineers to better understand and optimize design trade-offs for quality, cost and performance.

Reduce development and warranty costs
Simulation with NX Nastran is credited with driving millions of dollars out of R&D costs because building a computer model and digitally testing performance is cheaper, faster and more effective than the physical prototyping processes it replaces. And with increased product quality, companies can save on potential warranty costs.

Siemens’ CAE vision and heritage
Our vision is to deliver engineering simulation solutions that drive product performance decisions across the complete product lifecycle. Siemens PLM Software delivers on this vision by building upon our simulation heritage which spans over 40 years and encompasses well known CAE brands such as I-deasâ„¢, NX CAE and NX Nastran.
