Noran Engineering, Inc. in the Media

NEiFusion Receives Award from Design News Magazine

Design News magazine awarded Noran Engineering its 2007 Golden Mousetrap Award for Best Product in the Category of Analysis & Calculation Software for NEiFusion v1.2 . The award was presented at the National Design Engineering Show in Rosemont, IL in October. Pictured above is Dalis Ramonas, NEi Central U.S. Account Manager, accepting the award at the show. The award was particularly satisfying for NEi because Design News magazine is read by 170,000 subscribers involved in mechanical and electromechanical design and product development. Plus, NEiFusion was selected above many established brand names because of the many new features that make it an effective tool at the CAD design stage for virtual test and design validation.

Some excerpts from Design News’ assessment and selection process follow:

“Looking for finite element analysis (FEA) capabilities, but aren't an FEA simulation specialist? Look no further than NEiFusion , Noran Engineering Inc. 's new approach to engineering analysis and simulation software. The FEA program is designed specifically for engineers doing design and product development”.

NEiFusion takes a 3D, feature-based, paramatic CAD approach, making it feel more familiar and friendly to most within a product development team.”

“For engineers, more accessible and affordable FEA software opens the door to doing virtual testing earlier and more often in the design process. NEiFusion presents design engineers with an easy-to-use tool to assess the performance of their parts before prototypes are built, which aids in reducing design cycle times and boosting quality improvements.”

“The software's Pre-Processor module incorporates a comprehensive element library, meshing capabilities and an extensive materials liberty to insure real world fidelity. Its Post-Processor component provides a wide variety of images and graphs to view simulation results and is equipped with file sharing and import/export capabilities for easily sharing FEA models. NEiFusion also employs the same NEiNastran Solvers found in Noran Engineering’s other analysis products.”

Tech Tips

Using the Stress Error Quantification in NEi Nastran
A recently added feature of NEiNastran is a value which quantifies the stress error for shell and solid elements, addressing the issue associated with mesh density.

When using shell and solid elements for stress contours, it is difficult to know when you have enough elements to capture the stress adequately. To provide a guideline for using both the Shell Element Stress Error and Solid Element Stress Error to determine when enough elements have been used, we created test cases where we incrementally increased the mesh size for various models to determine the Stress Error value corresponding to a 2% stress convergence. The max von Mises stress was used to quantify the Shell Element stress error, whereas the max Normal Stress was used to quantify the Solid Element Stress Error.

For a von Mises stress convergence within 2%, a Stress Error of approximately 0.015 or less is needed for shell elements. To achieve a Normal Stress convergence of 2%, a Stress Error of approximately 0.03 or less is needed from solid elements.

Using the Extended Results Labels in NEi Nastran
There is now added support for extended results titles and labels in the FEMAP Binary results File (FNO). The new labels are now up to 80 characters long and provide a better description of the associated results measure.

The parameter RSLTFILEDBLERPRCS under Output Control Directives allows you to turn ON/OFF the double precision option for the FEMAP FNO. When set to OFF, it will use single precision data storage with extended length titles and labels. When set to ON, it will use double precision data storage with standard length titles and labels. The OFF option is only compatible with FEMAP versions 9.3 and higher an will provide better performance and more informative results labels.

In the two screenshots bellow you can see the difference in the results titles from when the RSLTFILEDBLERPRCS parameter is set to ON and when it is OFF. For example the shell element bottom side principle stress reads “SHELL MINOR-PRINCIPAL-1” when set to ON and “SHELL MINOR-PRINCIPAL-BOTTOM” when set to OFF.


Standard Length Titles and Labels, RSLTFILEDBLERPRCS = ON


Extended Length Titles and Labels, RSLTFILEDBLERPRCS = OFF

If you do not know what some of the result vectors are, you can look up descriptions in Appendix A of the NEiNastran Reference Manual. Simply go to Start>All Programs>NEiNastran> Documentation and open the NEiNastran Reference Manual PDF file. In Appendix A, results descriptions are separated into three types of results, Element, Grid Point, and Vector, and within each of these types they are separated by element type.

Noran Engineering Featured Application

NEi Nastran Helps Meet the Challenges of Composite Design for Around-the-World Ocean Racing

Farr Yacht Design (FYD) of Annapolis, MD has compiled an exceptional record of wins over the last 25 years in some of the world’s most prestigious yachting events. Successes include the Whitbread Round the World Race, now the Volvo Ocean Race, America's Cup, Admiral's Cup, Commodores' Cup, Kenwood Cup, Sardinia Cup, and Southern Cross.

When Dave Fornaro, FYD Design Engineer, was looking to enhance his composite structural analysis and simulation capabilities he looked to Noran Engineering. He put his thoughts on his expectations of FEA software this way, “Structural analysis is an increasingly important component of successful racing yacht design. We have been utilizing FEA for several years to validate and improve our designs and desired to enhance our suite of analysis tools with more advanced capabilities in several areas including laminated composites, non-linear surface contact with friction, and bolted joints with pre-load. After an exhaustive review, NEi Nastran stood out as the best choice based on its advanced capabilities, cost-effectiveness, and quality technical support. FYD’s first application of NEi Nastran is for it’s next-generation of designs for the Volvo Ocean Race, a grueling round-the-world race sailed in fully crewed, 70-foot carbon fiber yachts capable of speeds in excess of 40 knots. These designs are forging new frontiers in ocean racing. They operate in harsh and brutal conditions, and require a rigorous level of structural design and analysis to ensure peak performance and safety. We are confident that NEi Nastran will be an excellent tool for the job and we have been extremely satisfied with the support from Noran Engineering.”

Tony Abbey, NEi Technical Manager, noted the collaborative potential and the connection with other composite projects, “NEi Nastran provides benefits to a highly sophisticated user base ranging from aerospace vehicles and Formula 1 cars to America’s Cup and Tour de France bicycles. So we are excited to include FYD in our community of composite analysts.”

The Disney-backed "Pirates of the Caribbean" shown placed second in the 2005-2006 edition of the race. The grueling 9-month, round the world event covers some of the most extreme and inhospitable sailing conditions on earth, including winds up to 60 knots and ocean swells up to 30 feet high, with the boats capable of speeds in excess of 40 knots. Right : NEi Nastran Finite Element Analysis (FEA) software from Noran Engineering ( www.NEiNastran.com ) is used to simulate the performance of the entire yacht made from carbon fiber composites.
