Unprecedented speed of technology evolution
The Age of Exponential Thinking
The era of “Accelerating Returns” and a new balance of “Price, Performance, Capacity and Bandwidth”
Performance doubles every 18-24 Months
Moore’s Law1975
“...We better disrupt ourselves in our own way before somebody does an Uber to us.“ Doug Oberhelman, CEO CATERPILLAR @ CIW, Oct15, 2015

Reduced Order Models
13 © 2015 ANSYS, Inc. July 7, 2016 ANSYS Confidential
ROM creation example: Generic underhood test case
• 3D thermo-aerodynamic
• 2 parameters :
- Inlet velocity from 5 m/s to 20 m/s
- Exhaust Temperature from 700K to 900K Inlet velocity
Exhaust pipe
14 © 2015 ANSYS, Inc. July 7, 2016 ANSYS Confidential
Reduced Order Model generation process (learning process)
• 50 calculations were done– 10 were used to create the model
– 40 others used for verification
• ROM Model creation is 9 seconds
• Average error on velocity : 0,06 m/s
• Average error on temperature : 0,49 K– Quantitative differences in between
Fluent calculation and ROM model are presented on the worst verification point
