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.

The Survey of Verification and Validation Activities in Scientific Simulations

Verification and Validation (V&V) issues in scientific work in the area of computational mechanics are an important part of this master thesis discussion. In order to explore these problems a sort of survey has been carried out. The questionnaire can be found here (active until the end of May'07).

Although the questionnaire is focused on the area of computational mechanics, it is not limited for this group only. Similar processes, activities and problems occure in other branches of scientific computer simulations.

So if You are involved in scientific simulations, please take part in this survey and fill the form.

The agregated results for the survey will be available at this blog by the and of May'07. Conclusions will be published in June'07.
