CEM Validation-VERIFICATION AND VALIDATION OF COMPUTATIONAL ELECTROMAGNETICS SOFTWARE (original) (raw)

One of the most time-consuming tasks associated with developing and using computer models in electromagnetics is that of verifying software performance and validating the model results. Even now, relatively few available modeling packages offer the user substantial on-line assistance concerning verification and validation. This paper discusses the kinds of errors that most commonly occur in modeling, the need for quantitative error measures, and various validation tests such as convergence behavior and bounary-condition checks. Use of model-based parameter estimation to develop error estimates or to control uncertainty in an observable is demonstrate several examples. The article concludes by recommending that the Computational Electro-Magnetics community adopt a policy of requiring some minimal standards concerning the accuracy of numerical results accepted for journal articles and meeting presentations.
