V&V: Verification & Validation
in Engineering Simulation
2-DAY MASTER CLASS - 25th & 26th April 2017
Building simulation credibility in an industrial context
Engineering simulation plays an increasing role in industry’s search for competitiveness and technology based innovation at any stage of the design, qualification and certification of their products. Key decisions and product qualification/certification increasingly rely on virtual tests and digital simulations,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(V&V) of simulations 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 and 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…
Course objectives and benefits
This Master Class is especially dedicated to V&V methodologies for numerical simulation in Engineering. Participants will be able to adapt or tailor the course methodologies to their specific industrial context, and further improve their V&V processes and plans.
The course has been taught over 20 times since 2013 all over Europe.
Who should attend?
Programme/project managers who need to make critical decisions based on engineering simulation results and wish to increase their understanding and visibility of the required V&V activities
Participants should have a few years of experience in engineering simulation for the design and development of industrial products.
All industry sectors confronted with numerical simulation V&V are concerned with this course. It is established on the solid knowledge of the tutors and the vision they have developed from their rich industrial experience, mainly within the aerospace and nuclear energy sectors and is primarily illustrated by FEA/Structure Analysis examples. The course is therefore of greatest interest to engineers involved in this technical domain, but will also appeal to engineers from other simulation domains because most of the V&V methodologies which are presented are generic in nature.
The course is neutral and independent of any particular software solution.
We limit the number of participants to a small group to facilitate dialog and exchanges between participants.

Event Type: Course
Location: London U.K.
Date: April 25, 2017
This course is tutored by Jean-Francois IMBERT and Philippe PASQUET, high-level simulation professionals both benefiting from a long academic and industrial experience gained from leading companies. Their skills extend from numerical methods to solving industrial problems, especially in aerospace and nuclear area, and to analysis management. V&V is one of their key expertise, reason for which they have been asked for help by major European companies. They are recognised as one of the leading figures in the engineering analysis community in France.
The course is agreed and under control of NAFEMS Education and Training Working Group (ETWG).
