| Descripción: |
The complete design of many electromagnetic devices requires the solution of a coupled problem. Typically, the coupling is in the form of magnetic/thermal, magnetic/structural, magnetic/electronic, or possibly a combination of several disciplines. Computer based tools exist for many of these engineering specializations but they are usually "stand-alone" and each requires an experienced designer to use it effectively. This requirement for an expert user places a major constraint on the design cycle, and a lack of communication between the various experts can result in major design errors. This thesis proposes a software architecture that is capable of providing loose coupling between currently available design tools and of absorbing new tools in the future. The structure provides an integration environment for a suite of design programs. The environment automatically allows the iterative solution of coupled problems by loosely coupling individual tools through a comprehensive database and organizing their execution via a rule-based control program. In order to effectively integrate a diverse set of tools and to define the kind of coupling between the various analyses, it is necessary that the input and output requirements of each tool be carefully defined. The BlackBoard for Computational Analysis and Design (BBCAD) is a hybrid knowledge-based system which uses the blackboard architecture, and generates a systematic method of integrating the "stand-alone" design tools, together with an automatic method of ensuring that, if a change is made to the design, all the relevant design tools are re-run. |
