Verification & Validation in Engineering Simulation

Verification & Validation in Engineering Simulation



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… 

The Course

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 of expectation due in their industry context and applicable regulations

  • Understand the fundamental concepts of V&V, the role and contents of standards, the existing methodologies for the implementation or the improvement of simulation and V&V plans

  • Understand specific V&V requirements in the context of realistic simulation and virtual testing

  • Understand how to build rational plans for V&V and related demonstrations

  • 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 management and process issues

  • Learn how to implement reporting to bring visibility and confidence to all managers concerned with simulation outcomes.

Who Should Attend?

This master class course is designed for:

  • Engineers and senior analysts in charge of simulation activities or preparing to take new responsibility in the management of simulation, especially with regard to V&V responsibility

  • Managers in charge of engineering simulation teams and willing to improve their knowledge in V&V and in the relevant processes

  • Program managers who need to make critical decisions based on engineering simulation results and that wish to increase their understanding and visibility of the required V&V activities

It is recommended that participants have a few years of experience in engineering simulation for the design and development of industrial products.
