Abstract

Definitions and equations are provided for quantitative assessment of numerical (verification) and modeling (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 are presented of quantitative V&V for RANS and DES simulations and certification of RANS codes for ship hydrodynamics applications. Opportunities and challenges for achieving consensus and standard V&V and certification methodology and procedures are discussed.
