This paper discusses Verification and Validation for CFD applications. It emphasizes the differences between the mathematical problem of “solving the equations right” (Verification) and the science/engineering activity of “solving the right equations” (Validation). A clear distinction is made between Code Verification (error evaluation) and Solution Verification (error estimation) and procedures based on grid refinement studies are presented and discussed for both activities. The paper presents examples of Code Verification for Reynolds-Averaged Navier-Stokes solvers using the Method of the Manufactured Solutions; Solution Verification exercises including the KVLCC2 tanker at model and full scale Reynolds number and two examples of the application of the ASME V&V 20 Validation procedure. This paper is written to stimulate a conscientious approach to CFD in marine applications.
