Abstract : The Research and Engineering Framework (REF) manages data for a variety of design and analysis codes. Each of these different codes has its own data requirements (data model) for input and output. The method that the REF uses to handle these different data models is through the use of a data dictionary. By utilizing the data dictionary, REF users will have the ability to switch between data models thereby transforming the generic REF into a discipline specific design system. This report documents the effort to design and develop a computational electromagnetics (CEM) specific data dictionary for the REF. Types of data covered by this dictionary include: CEM analysis techniques, geometry elements, material properties, excitation information, and observables information. The CEM data dictionary has been developed as a baseline data dictionary for the wide variety of CEM codes available. A developer need only tie his/her application specific code into the REF directly or through a code interface wrappering to access this data dictionary.
