Quantitative V&V of CFD simulations and certification of CFD codes

TLDR

The paper defines equations for quantitatively assessing numerical and modeling errors, uncertainties, and certification intervals in CFD simulations. It describes verification, validation, and certification procedures for CFD codes. The authors apply the quantitative certification framework to RANS ship‑hydrodynamics simulations, illustrating practical examples and the challenges of establishing consensus V&V standards. © 2005 John Wiley & Sons, Ltd.

Abstract

Abstract Definitions and equations are provided for the quantitative assessment of numerical (verification) and modelling (validation) errors and uncertainties for CFD simulations and of intervals of certification for CFD codes. Verification, validation, and certification methodology and procedures are described. Examples of application of quantitative certification of RANS codes are presented for ship hydrodynamics. Opportunities and challenges for achieving consensus and standard V&V and certification methodology and procedures are discussed. Copyright © 2005 John Wiley & Sons, Ltd.
