My presentation: "The Survey of Verification and Validation Processes for Large Scale Simulations in Computational Mechanics".

ABSTRACT

KEYWORDS: computational mechanics, simulation, verification, validation, benchmark database

Verification and validation (V&V) of simulation models, code and solution are requisite for the approvement of the scientific simulations.
These issues were first studied from the scientific literature [1, 2, 3, 4, 5, 6] and discussed with engineers. Then a sort of survey was conducted to check how the situation really looks like.

The presentation shows the current situation for V&V activities in the area of computational mechanics. The different approaches to model validity and code verification are presented. Various V&V techniques are defined and data validity is prescribed. The question: ”How to improve the processes of V&V and how to make them easier?” is tried to be answered.

One of the conclusion is that there is a strong need for benchmark databases to help scientists to verify and validate their numerical models, software and simulation results.
