This paper presents our methodology for verification and validation (V&V) of models, coupled to quantification of risk and risk reduction, and the use of risk, quantified as a dollar value, in the value-engineering and decision trade-off process. We

One of the final steps in building a numerical model of a physical, mechanical, thermal, or chemical process is to assess its accuracy as well as its sensitivity to input parameters and modeling technique. In this work, we demonstrate one simple proc

The concepts of Verification and Validation (V&V) can be oversimplified in a succinct manner by saying that 'verification is doing things right' and 'validation is doing the right thing'. In the world of the Finite Element Method (FEM) and computatio

Grid convergence is often assumed as a given during computational analyses involving discretization of an assumed continuum process. In practical use of finite difference and finite element analyses, perfect grid convergence is rarely achieved or ass
