NEiNastran
V9.02 Update
The NEiNastran
Engine is a powerful, general purpose finite element analysis
solver used to analyze linear and nonlinear stress, dynamics,
and heat transfer characteristics of structures and mechanical
components. The V9.02 update contains several enhancements and
bug fixes to the V9 release of the NEiNastran Engine. The major
enhancement of this update is reduced runtime for frequency and
transient response analyses with complex loading. Analyses that
took several hours can now be run in several minutes.
An example
of NEiNastran V9.02 capabilities is this nonlinear transient analysis
of a rubber membrane. The simulation involves large displacements,
rotations, and post-buckling behavior. Click here

Nastran FEA Granted Certified Gold Product Status by SolidWorks
Noran Engineering
has received Certified Gold Product Status from SolidWorks Corporation
for NEiWorks®, for its Nastran finite element analysis (FEA)
program embedded in SolidWorks® 3D mechanical design CAD software.
SolidWorks Certified Gold Product status is conferred after rigorous
testing by a corporate certification team to insure compliance
with the highest level of integration, associativity, and compatibility.
NEiWorks’
groundbreaking product strategy departs from industry practice
by embedding Nastran FEA and providing wide scale Nastran data
sharing. The result is sophisticated SolidWorks users who need
high level Nastran FEA capabilities get a dramatic boost in productivity
and design speed because NEiWorks eliminates model import issues,
takes full advantage of SolidWorks solid modeling technology,
and allows the transport of FEA data across the full community
of Nastran users, including analysis products NEiNastran®,
MSC.Nastran®, and NX Nastran®. SolidWorks users are the
first CAD audience to have this embedded Nastran FEA path.
Dave Weinberg,
Noran Engineering’s CEO, emphasized the value in this innovation,
“NEiWorks offers an exciting direction for FEA technology.
By eliminating CAD geometry issues and allowing wide file sharing,
our state-of-the-art Nastran performance makes engineering simulation
easier, faster, and significantly more cost effective.”
Efrat Ravid,
Partner Program manager for SolidWorks, commented, “We are
delighted that the innovative efforts of Noran Engineering and
the Gold Product program can benefit the Nastran FEA community
within SolidWorks.”

Applications
ShipLift Project Illustrates Innovation and Customization Potential
with NEiNastran FEA
Noran Engineering,
Inc. is working with ShipConstructor Software USA Inc. of Victoria,
British Columbia on software that could help move ship parts damage-free.
ShipConstructor makes three-dimensional product modeling software
for the maritime industry.
The application,
codenamed ShipLift, would calculate the proper pickup points to
move ship sections, parts, and sub-assemblies. A 3-D model of
the structure would be created in ShipConstructors’s design
software, NEiNastran would analyze the model for stresses and
strains on pieces, and then the best pickup points for safe free-lifting
and handling would be identified. Lifting calculations and operator-handling
instructions would be included on the models of the ship parts.
All the information would be stored, so any changes to the model
would automatically update the FEA calculations.
Dave Buckman,
Noran Engineering's Maritime Accounts specialist observed, “This
is a great illustration of how NEiNastran FEA software can easily
and economically be modified to accomplish value added tasks for
specific industries. This will be major cost savings for shipyards.
They can eliminate high rework costs and avoid expensive disruptions
in their production cycles."
The US Navy
is funding the joint project through its Small Business Innovative
Research program.
Cervélo
Cycles Ratchets Up Technical Performance on Next Generation Racing
Bikes
Noran
Engineering announced that Cervélo Cycles, a manufacturer
of professional competition road and triathlon bikes, has selected
a portfolio of Noran Engineering’s finite element analysis
software for use in product development. Cervélo explained
that the level of design sophistication in the bicycle industry
has been steadily increasing and computer aided engineering tools
are needed to meet the challenges of optimizing engineering materials
like carbon composites and extending design metrics like strength
to weight ratio, vibration characteristics, and flexural stiffness.
“We chose Noran Engineering’s NEiNastran because of
its accuracy, functionality, and demonstrated value in similarly
demanding applications,” said Don Guichard, Director of
Engineering for Cervélo Cycles.
Cervélo
most recently introduced a super-light carbon frame with high
stiffness-to-weight, the Soloist Carbon-SL, and provided bikes
in this year’s Tour de France to Team CSC which earned two
stage wins by Jens Voight and Frank Schleck, earned second in
the team classification, and saw Carlos Sastre finish fourth overall.

Tips
Creating
Loading Regions in NEiWorks
If
you would like to create a load, but your surface may not be appropriate,
here is some help. For example, you have a model of a stapler
and you want to simulate the load while using it. If your model
has one surface for the top but you only want to load one section
of that surface, here is what you can do:
| ·
|
For
this example you want to create a circular loading patch on
the top surface of your stapler. The first thing we need to
do is sketch a circle on the top surface of the block. |
| · |
Once
you have this, click on Insert > Curve > Split
Line. Select Projection as the Type
of Split. Select the sketch with the curve and the top face
you would like to section. It will create two separate surfaces. |
| · |
When
you re-mesh the solid, you will see that you have a defined
region for applying loads. |
You
can also use this trick for re-meshing regions. Follow the above
steps and then you can use the Advanced Meshing Options to re-create
your mesh.
Creating
