摘要:The numerical simulation and digital solution of many engineering problems in solid mechanics,fluiddynamics and a wide range of other fields is now widespread.Design processes rely more and more on the results ofCAE modelling,bringing an increased need to ensure that those results are reliable—not only in the verification ofbasic algorithms and their embodiment in computer code,but also at the level of the processes by which these codesare used and the good judgement of the people using them.The‘fitness for purpose’of any modelling and analysisprocess must be established:firstly its‘purpose’一in design,optimization,certification and SO on—and then its‘fitness’.This paper addresses the requirements for benchmarking and quality assurance of CAE methods;theirappropriate application and integration into engineering design and certification processes;and the education andtraining—and potential accreditation—ofusers.The NAFEMS organization has existed for OVer 25 years—commencing in the UK and growing into a worldwide,independent association for the engineering analysis community—dedicated to addressing these needs in all’independent and unbiased wayr
