Learn about the fundamentals of Analysis Led Design and how CSEG can help you to reap the benefits of the analysis packages you already own.

1. What is CSEG?
Computational Sciences Experts Group,
LLC

2. We are a group of experts in simulation
 We hire best and the
brightest
 Everyone has a LOT
of experience doing
simulation
 We are very fast at
what we do (and we
will teach you how
to)

3. Who needs CSEG?

4. MOST COMPANIES WANT TO
DO
MORE
SIMULATION
(TO REDUCE PROTOTYPES AND SAVE MONEY, OF COURSE)

5. BUT THE REALITY IS…

6. “We are focused on delivering product
and don’t have time to
develop our simulation methodologies”
(but we talk about it in every meeting on how we need to
do more simulation)

7. OR
do not
“We are investing in the software, but
have the complete know-
how to get it to do what we want to do.”
(But we will never admit it)

8. OR
“We’d like to do simulation but buying
the right software tools, training and
developing people
seems daunting!”
(So we will continue to test and just claim that simulation
does not work)

9. YOU NEED CSEG.
We don’t sell software. We bring our modeling expertise
and make your CAE software do
advanced stuff.
The stuff you bought the
software to do to begin with.

10. WHAT KIND OF
SIMULATION?

19. HOW WE DO IT?

20. Our Approach
• We focus on the problem, combining the right
tools to provide accurate answers for your simulation
challenge – not the tool any one company is selling. CSEG
maintains licenses for best in class COTS tools providing instant
technical capability expansion to your projects.
System Tools CFD Tools
• Flowmaster* • Ansys Fluent
• Amesim • STAR-CD
• Gamma Technologies
Other
Optimization Tools • Matlab/Simulink
• iSight* • Can integrate your
• ModeFrontier in-house software
with COTS

21. Our Services
1. Calibrate: 2. Integrate:
We integrate various
We build accurate
simulation tools for a
simulation models and
specific problem to
calibrate them with test
reduce error and
data
improve accuracy
4. Optimize: 3. Interface:
We build optimization We build simplified
tools or integrate with interfaces for complex
existing ones to models to enable faster
optimize key variables and wider use of
in the system simulation models

22. Our Deliverables
• Detailed simulation report with simulation results,
inferences, possible design changes, software used,
modeling approach, physics assumptions etc.
• Simulation models (for e.g., Flowmaster models, CFD
models) of the system that was built.
• Training on simulation models and modeling approach
• Recommended process to tackle similar problems in the
future.
• Help you positively identify the right tools for such
problems.

23. We’ll transfer this
know-how to your
team along the way
