UGS Launches NX Nastran Version 3
UGS announced immediate availability of NXT Nastran Version 3, the latest release of the company's software solution for advanced finite element analysis (FEA).
"NX Nastran Version 3 is very significant for UGS," said Chuck Grindstaff, executive vice president, Products. "It is visible proof of the energy and commitment of our development team in delivering customer requested enhancements and capabilities that will be used around the world - in industries from automotive and aerospace to heavy equipment, biomedical and consumer products. We believe our customer centric approach provides competitive advantages for our customers."
"Today's advanced noise, vibration and harshness (NVH) analysis applications require seamless integration of special-purpose proprietary software tools into the analysis process," said Dr. Otto Gartmeier, manager, NVH DaimlerChrysler AG. "NX Nastran sets new standards in solver technology and enables us to extract maximum benefit from the FEA tools that are core to the virtual development process."
"UGS' development approach to solving large numerically complex problems gives NX Nastran the ability to leverage our most advanced platform technology," said Norman Lindsey, CAE Solutions Engineering Manager, High Performance Computing, HP. "We believe this not only meets the needs of our most demanding customers, but also positions UGS for providing market-leading advanced analysis going forward. UGS customers are able to take advantage of raw performance for driving products to market much faster."
NX Nastran Version 3 - Major Enhancements
Analysis Solution Performance
• Hierarchical Distributed Memory Parallel (HDMP) Processing - provides users with the ability to solve extremely large scale dynamics simulations in much shorter elapsed times. This is possible through new NX Nastran scalability that allows up to 64 simultaneous CPUs in a cluster configuration versus the previous limit of eight simultaneous processors. This improved high performance computing scalability is unique to NX Nastran and is particularly valuable to CAE applications in the automotive, aerospace, defense, heavy equipment and shipbuilding industries that require extremely large scale, compute-intensive analysis.
• Complex Eigen Solver Performance - provides up to 40 percent improvement over NX Nastran Version 1 for typical complex dynamics applications, such as brake squeal analysis, rotor dynamics, etc.
New Advanced Nonlinear Module
NX Nastran Version 3 includes a new advanced nonlinear capability (Solution 601) based on the world-class ADINA non-linear structural analysis solver technology that is now integrated and branded within NX Nastran. Users of NX Nastran will now be able to perform much more advanced nonlinear simulations while continuing to use their standard Nastran® input and output file formats and Nastran simulation work processes. Application areas for this new NX Nastran technology cut across all major industries but are especially relevant to simulation needs in automotive powertrain, off-highway equipment, consumer products, process/rotating equipment, aircraft engines and defense.

Nastran Analysis Efficiency
• Enhanced CQUADR/CTRIAR Shell Element - provides an easier to use finite element that is more versatile than previous versions of this type of membrane element.
• Shell Element Thickness Variation control allows for ease of use as a design variable in optimization.
• MAX/MIN Results Post-Processing - significantly reduces the amount of results data that must be stored during the analysis process and eliminates additional post-processing outside of NX Nastran to determine maximum, minimum or RMS stress results for modal transient simulations.
• Integration with other widely used digital simulation tools
• Provides ability to export flexible body finite element models from NX Nastran to MSC.ADAMS via a .mnf file.
• Expands NX Nastran integration with the world-class CAE desktop modeling and results visualization tools available within NX, I-deas® MasterFEM and Femap® digital simulation software solutions.
• Desktop-only versions of NX Nastran Version 3 are available for use with the latest releases of NX digital simulation solutions, including NX Scenario, I-deas NX MasterFEM and Femap.
