Nowadays, modelling and simulation is common practice in engineering and its results may be important for making decisions. Therefore, the credibility of the results obtained must be assessed. In the numerical solution of physics based models, which are the most usual in Computational Solid Mechanics (CSM) and Computational Fluid Dynamics (CFD), verification, validation and uncertainty quantification (VVUQ) are the activities that allow to establish the credibility of modelling and simulation. Several organizations, as for example ASME, AIAA and NAFEMS have published documents about best practices in VVUQ that can help engineering practitioners to apply VVUQ and understand its benefits. The proposed Mini-Symposium will address many aspects of verification, validation and uncertainty quantification based upon the contributed abstracts. The following topics are suggested by the organizers: • Standard techniques to perform Code Verification, Solution Verification, Validation and Uncertainty Quantification activities. • Description and explanation of published VVUQ standards and guides. • Application of VVUQ techniques to practical engineering problems.
