13 Confidential | 1. Automation  Example : front door static stiffness evaluation  Over 40 different load cases  Each time have to setup the model, launch calculation, post process and make the report Average 13 hrs

14 Confidential |

15 Confidential |  Benefits & Perspectives 1. Automation  625 man days (3 engineers) of manual work saved  This workforce can be used for value added tasks such as Optimization and Counter-measures.  Opportunity to deploy automation for other Openings calculations

16 Confidential | 2. Innovation : Using Radioss for Airbag Deployment Simulation Methods • UP : Uniform Pressure – Pressure is constant anywhere within the airbag volume – Gas property, injector, vent holes, and jetting effect can be setup on the monitored volume – Multiple chambers can be defined • CEL : Coupled Euler Lagrange – Airbag set into a « cube » of air (Euler/ALE 3-D hexa) – Airbag fabric (Lagrange 2-D shell) coupled with a specific CEL fluid/structure interface (TYPE18) – Gas flow computed using ALE (Arbitrary Lagrange-Euler) method • FVM : Finite Volume Method * – Air inside the bag automatically/transparently meshed and re- meshed during the computation – Airbag input almost same as in Uniform Pressure input card – Gas flow computed using ALE method  LOCAL LCI in India – Collaborative innovation laboratory – is developing inflating parts. Need to simulate inflation and deflation time

17 Confidential | 3. Inspire • Turn table • Seat • Chassis

18 Confidential | Inspire Example #1 - TurnTable Filling the design space and applying boundaries  Rotating table concept

19 Confidential | Inspire Example #2 – 3rd Row seat base bracket Pivot points Seat Base mountings Base Bracket Details  3rd row seat base bracket design optimization

20 Confidential | Inspire Example #3 - Chassis Cas 1 Fx = +xxxN (effort centre roue) Fy = +xxxN (effort pied de roue) Fz = -xxxN (centre ressort) Cas 2 Fx = -xxxN (effort centre roue) Fy = -xxxN (effort pied de roue) Fz = -xxxN (centre ressort) Pied de roue Centre roue Centre ressort  Local project chassis part mass reduction

21 Confidential | Head lamp mounting brackets are considered as the design variable to meet crash performance and NVH performance of the head lamp assembly 4. MDO – Case study  Headlamp support Bracket combined NVH/Crash Optimization

22 Confidential | Target responses: Crash Requirement: The contact force should be less than 3500 N NVH Requirement : The first Natural Frequency should be more than 30 Hz Min / Max Thickness allowable: Min Thickness Allowable is 0.8mm Max Thickness Allowable is 1.8mm 4. MDO – Benefit  Thickness is optimized to reach both NVH and Crash targets at the same time

23 Confidential | Conclusion Partnering with Altair in India main benefits:  Help reduce the lead time with automation  allow more time for added value tasks  Support for new technologies development and competencies ramp-up  Leverage latest technology innovation  Enhance capabilities for C/M studies on project development  simulation driven design
