This recommended practice serves as an aid to CEM modelers and analysts in the selection and application of appropriate computer modeling and simulation methodologies, physics, and solution techniques to achieve accurate results. It also serves to complement measurements and EM design tasks for a range of progressively complex problems through the use of modeling problem examples for small-to-large scale canonical, benchmark, and standard validation problems. Finally, this recommended practice provides a detailed description of a validation process, i.e., the Feature Selective Validation (FSV) method, which compares a particular solution data set to a reference data set.
