Verification and Validation in Engineering Simulation

Verification and Validation
in Engineering Simulation

9 - 11 November 2020, Online (Webex)

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 computational 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 simulation 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 and credibility assurance methodologies for numerical simulation in Engineering. Participants will:

  • Develop their knowledge in V&V including fundamental concepts, most recent methodologies and contents of existing standards.
  • Understand essential links between the product validation/certification and simulation V&V.
  • Learn how to plan and prioritize simulation V&V including physical tests programmes.
  • Understand validation test issues and improve synergy between virtual and physical tests in the context of validation.
  • Learn how to build business cases allowing for justification of V&V plans.
  • Understand simulation V&V organisation and management issues and best practises
  • Learn how to implement reporting to bring visibility and confidence to all managers concerned with simulation outcomes.
  • 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 39 times since 2013 all over Europe.

Who should attend?

  • Primarily experienced engineers and senior analysts in charge of simulation activities or preparing to take new responsibility in the management of simulation, especially regarding V&V responsibility
  • Managers in charge of engineering simulation teams and willing to improve their simulation V&V knowledge
  • Programme/project managers and stakeholders from regulatory bodies who need to make critical decisions based on engineering simulation results and wish to increase their understanding of simulation V&V.

Participants should have a solid experience in engineering simulation for the design and development of industrial products.

Course context

Are concerned with this course all industry sectors confronted with numerical simulation V&V, and primarily those sectors where simulation is playing a critical role for the product design or certification. The course 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.
