Linear: General Motors
RADIOSS Momentum
Challenge: Increase solution accuracy achieve higher
through-put at little or no additional cost.
Solution:
• RADIOSS replaces NASTRAN
• Improved model accuracy via thorough checking of
input data
Business Impact:
Increased throughput:
• The HyperWorks licensing model provides an increased
number of solver licenses at no additional cost
• Speed of AMLS solver algorithm solution
RADIOSS delivered to GM a cost effective yet very accurate solution. Also, the combination of
increased number of licenses (thanks to the patented HW licensing model) and AMLS dramatically
increased the overall through put.

Non-Linear Implicit: Progress-Werk Oberkirch
RADIOSS Momentum
Challenge: Combine the often conflicting product
specifications defined by the customer while developing
the component in a timely and cost effective manner
Solution:
• Apply HyperWorks throughout the development process
• Utilize RADIOSS for both implicit and explicit analysis
• Validate the product manufacturability for sheet metal
parts
Business Impact:
• Reduce development time while accelerating innovation
• Maximize the Return on Software Investments
• Improve product quality and process robustness
“We were looking for a reasonably priced product family with which we could cover all simulation
tasks throughout our entire development cycle up to production. […] Without HyperWorks we could
not develop and produce our products as efficient and quickly as with the CAE suite.”
– Michael Welle, Development Product/Process, Numerical Simulation, Progress-Werk Oberkirch AG

Non-Linear Explicit: PSA Peugeot Citroën
RADIOSS Momentum
Challenge: Define a new simulation process
development that includes accurate component data
(thickness, residual strains, etc.)
Solution:
• Use HyperForm and RADIOSS in product development
• Evaluate the impact of the manufacturing process onto
the component formability
• Seamlessly include forming results into RADIOSS
crash simulations
Business Impact:
• Reduce overall development time
• Get a better correlation with test results
• Improve product quality and process robustness
Different deformation pattens (Reference, Without and With Blankholder) at 0,008 Sec
“We are in the position to predict crash results via simulation much better than in the past. Building
on this approach will lead to sustainable time savings and better products for our customers.”

CFD: Visteon
RADIOSS Momentum
Challenge:
Simulate highly transient flows in complex geometry that
include solar and enclosure radiations.
Solution:
• AcuSolve provides accurate transient solutions
• High speed parallel view factor computation
• Thermal shells technology used to simulate the effect of
sunroofs, moonroofs, doors etc.
• Fewer meshing constraints compared to finite volume
codes provided by competition and hence making it
easier to simulate complex geometries easier.
Business Impact:
• Improved CFD process for virtual prototyping.

• Robust, accurate and Fast solution methodology
improves user productivity
AcuSolve Product Suite is embedded in the Simulation Based Design strategy at Visteon.
This dramatically increased the overall through put and established a robust and accurate CFD
simulation methodology.

Multi-Body Dynamics: Volkswagen Motorsport
RADIOSS Momentum
Challenge:
Find the best suspension setup simulating standard
tests of race vehicles in extreme conditions, such as
kick-backs over an artificial hill.
Solution:
• Parametric modeling using MotionView.
• MotionSolve for vehicle Dynamics simulations.
• Correlation of the results with experimental test
Business Impact:
• Optimal suspension setup to improve the race
performance
• Fast and stable simulations with MotionSolve.
• Close match of parametric virtual studies and
physical test
“We were able to run fast and stable simulations, getting a close match between test and simulation
data and a better understanding on the effect of payloads on kickback.”
