New Product Development
NEiFusion-
A “Must-See” Analysis and Simulation Product
New Combination of Parametric CAD Technology and Nastran
Makes Design and Analysis a Natural Fit
Limited
Time Offer, Complete Package $1999
The mid level
market for analysis software has long been a problem for companies
looking to get into FEA or trying to expand its use within their
organization. FEA products that fit tight budgets had deficiencies
that were hard to accept, such as, cumbersome model creation,
inadequate post processor results presentation, limited analysis
types, poor solver accuracy, lack of industry recognition, and
the need to relearn new software systems and make large new investments
if higher level analysis capabilities were needed.
Now Noran
Engineering has an exciting new software package called NEiFusion
that not only addresses this market need but goes beyond by addressing
a number of long standing problems in traditional analysis software.
In NEiFusion, NEi has sought out the best in class 3D CAD geometry
engine for pre and post processing and combined it with highly
accurate and industry proven NEiNastran solvers. The solid modeling
technology in NEiFusion provides a 3D CAD environment that is
powerful and immediately familiar to your development team of
design, product, test, and quality engineers. User friendly and
loaded with tools, NEiFusion makes FEA model creation and the
exploration of design alternatives a natural part of the design
process. The Nastran solvers insure accuracy and wide industry
recognition and acceptance.
Why wait to
build prototypes to find out if your design will work? Do virtual
testing in your computer on different configurations, materials,
loads, and constraints. NEiFusion handles a full range of structural
and thermal problems. For an online demo of NEiFusion, go to www.nenastran.com/NEiFusion.
Noran Engineering
will be starting its marketing program for NEiFusion shortly with
press releases and advertising. However, early adopters will get
a very special limited time introductory offer. NEi will
sell a limited number of NEiFusion licenses at $1999 which is
an incredible savings of $3500 off the regular price.
If you have been considering FEA software, the introductory pricing
and money back satisfaction guarantee means this is the time to
act. Go to www.nenastran.com/NEiFusionPromotion.
NEiNastran
Engine V9 (x64 Windows)
Just what
you all have been asking for, the new 64-bit compatible NEiNastran
Engine will be released this month. NEiNastran x64 also includes
a new high-performance solver that adds:
| ·
|
Extremely
fast parallel direct solver capable of handling models over
15 million degrees-of-freedom |
| · |
Increased
efficiency and performance using supernode techniques with
update and pipelining parallelism |
| · |
Supernode
pivoting ensures numerical stability and scalability during
factorization |
| · |
Parallel
scalability is nearly independent of the shared-memory multiprocessing
architecture (performance increases of seven times using eight
processors have been observed) |
| · |
Handles
non-positive definite matrixes |
| · |
Accuracy
measure output |
Best of all,
this will be supported in all NEiNastran solutions!
NEiNastran
V9.1 is in development! Here are a few of the added new features
that are in the current V9.1 beta.
| ·
|
Added
von Mises stress output for bar and beam elements |
| · |
Reduced
processing time for element strain energy results |
| · |
Reduced
processing time for dynamic response analysis with complex
loading (Frequency and Transient Responses) |
| · |
Added
a new, more accurate triangular plate bending element |
| · |
Added
mass and stiffness DMIG support for the PCGLSS solver modes |
| · |
Added
support for large strain hyperelastic and large strain nonlinear
elastic materials for solid elements |
Many more
features are planned and underway. We will update you as additional
features are added. Please contact us with suggestions or comments
for what you would like to see in our next release!
Events
and Trade Shows
NEi
participated in a number of trade shows this past quarter. Here
is a look at some of these events.
Composites
product design, quality, and test engineers visited Noran Engineering
at the SAMPE Fall Technical Conference in Dallas, TX, November
6-9.
NEi's Technical Director, Tony Abbey, gave a presentation
entitled “NEi Nastran FEA for Composite Products with Case
Studies". Visit the Knowledge Center on the website to get
a copy of it.
Aerospace
Design Expo 2006 North America, November 14-16 at Anaheim Convention
Center, CA.
This exciting new trade show brought together professionals from
aerospace design and development teams responsible for software,
materials, avionics, rapid prototyping, modeling, and components.
They represented civil, military, and space industries. The three-day
exhibition was a showcase for all aspects of the aerospace design
industry from concept and innovation through to design and development.
The
Society of Naval Architects and Marine Engineers (SNAME) Technical
Conference and Exposition in Ft. Lauderdale, FL
The SNAME conference housed over 150 booths serving the shipbuilding,
design, technology, and production sectors of the industry. Dave
Weinberg presented a paper reviewing new applications of the FEA
method in the maritime industry. Visit the Knowledge Center on
the website to get a copy. The picture below is Dave Buckman,
Maritime Accounts Manager, enjoying a quiet moment before the
exhibition doors open and his morning coffee kicks in.
The Air Tec show in Frankfurt, Germany was a great meeting
ground for international aerospace companies. Dr. Bert
Schweitzer of SI-Schweitzer Ingenieurgesellschaft MBH, NEi’s
representative in Germany was able to offer his many years of
extensive experience in aerospace simulation to visitors.

Surface Differences
NEiNastran
Modeler is set up so that there are two types of surfaces. There
are boundary surfaces which are defined by the curves, and there
are parasolid surfaces which are generally ruled surfaces.
The parasolid surface can be treated like a solid. This means
that all the options in the Geometry > Solid
menu can be used on parasolid surfaces as well, such as slice
and add.
To convert
a boundary surface to a parasolid surface, you can go to Geometry
> Surface > Convert.
