Verification & Validation of Models and Analyses
Engineering simulation plays an increasing role in industry’s search for competitiveness and technology based innovation at every stage of the design,qualification and certification of products. Key decisions and product qualification/certification increasingly rely on virtual tests and digital simulation, creating a major paradigm shift in which the objective of physical tests is progressively moving from a demonstration of compliance to a reference for analysis validation. This trend in industry is shown through adoption of new terms such as ‘realistic simulation’ and ‘virtual testing’. This situation creates new responsibility for the engineer to guarantee the required confidence level.
This new approach requires secured processes for the verification and validation of models and analyses bringing evidence of their predictive capability. In particular, programme managers now require formal evidence on“simulation fit for purpose” on which they can build confidence and take decisions. In addition, the increasing situation for extended enterprise creates new constraints to guarantee safe and robust analysis processes.
At the same time, and due to the economic pressure, V&V activities are frequently seen as an additional cost that can easily be reduced or even fully cut, thus underestimating the induced risks. In addition, V&V is not easy to implement because of the diversity of involved persons: managers, simulation experts,test specialists, software developers and quality controllers, software vendors…
Participants of this master class will:
- Learn how to implement reporting to bring visibility and confidence to all managers concerned with simulation outcomes.
- Develop their knowledge in V&V in full coherence with the level ofexpectation due in their industry context and applicable regulations

- Understand specific V&V requirements in the context of realistic simulation and virtual testing
- Understand how to build rational plans for V&V and relateddemonstrations
- Improve synergy between virtual and physical tests in the context ofvalidation
- Learn how to build business cases allowing for justification of V&Vplans
- Understand simulation management and process issues
- Learn how to implement reporting to bring visibility and confidence to allmanagers concerned with simulation outcomes.

This course is tutored by Jean-Francois Imbert and Philippe Pasquet ,high-level simulation professionals both benefiting from extensive academic and industrial experience gained from leading companies. Their skills extend from numerical methods to solving industrial problems, especially in the aerospace and nuclear area, to analysis management. V&V is one their key expertise, and they have assisted many leading European companies in this area. They are recognised as ones of the leading figures in the engineering analysis community in France.
Jean-Francois Imbert has 40 years’ experience in Structural Engineering, CAE/ numerical simulation, mostly in the aeronautical and aerospace sectors where he has exercised both operational, expert and management responsibilities.Throughout his career, Jean-Francois ensured the development and implementation of innovative numerical simulation capabilities in industrial contexts, mostly in Structure Analysis. In his successive responsibilities, he accumulated a unique and broad experience in simulation management and the multiple features of V&V, including validation tests and analysis /test synergy. Furthermore he has a long practice of engineering education both in academic institutions and professional seminars.
With almost forty years of extensive experience in engineering simulation, Philippe Pasquet has covered the full range of technical responsibility in this domain, both with research institutes and various consulting firms and software houses: development of software, development of methods, advanced studies, team management, scientific and technical management etc. Powered by his passion for pedagogy and simulation technology, he has presented at several conferences and talks at high level towards efficient use and good practices of simulation in the industry, motivating students and engineers for those fascinating engineering simulation jobs.
