Evolution of the Role of CAE
Modern Simulation Environments
“CAE is evolving from being a set of
‘black box tools’ for highly
specialized individuals toward a
group productivity environment
that delivers strategic competitive
advantages to the business by
supporting simulation-driven design.”

•Reduced physical
prototypes by 30%
• Improved time to
market and product
quality
“Since introducing NX, we
are able to perform
repeated simulations
during the design stage.
This has helped us
reduce our development
lead times and lower
prototyping costs.”
Shinji Yoda General Manager

“The ability to work in a
highly integrated
environment, where design
concepts could be quickly
evaluated against all
requirements, was critical to
the success of this program.”
