14、rinted.FOREWORDSince the mid-1960s,computer simulations have come to dominate engineering mechanicsanalysis for all but the simplest problems.With todays increasing reliance on complicated simula-tions using computers,it is necessary to use a systematic program of verification and validation(V&V)to
15、ensure the accuracy of these simulations.This document is intended to describe sucha program.The concept of systematic V&V is not a new one.The software development community haslong recognized the need for a quality assurance program for scientific and engineering software.The Institute of Electric
16、al and Electronic Engineers,along with other organizations,has adoptedguidelines and standards for software quality assurance(SQA)appropriate for developers.SQAguidelines,while necessary,are not sufficient to cover the nuances of computational physics andengineering or the vast array of problems to which end-users apply the codes.To fill this gap,the concept of application-specific V&V was developed.Application-specific V&V has been the focus of attention for several groups in scientific andengi
