Abstract : This report attempts to review the existing need and tools as opposed to component design. In doing so, it illustrates the peculiar nature of design where concentrated contacts are involved. The point is made, that the concentrated contact local thermomechanical event cannot be ignored in the global system destruction. The cross-coupled sensitivity of local and global events demands understanding prior to hardware commitment. Such understanding is noted to be available in a variety of programs. The use of software, however, requiries an intelligent selection and assurance that results computed are meaningful. Therefore, notes are made concerning good software design, its architecture, and particular modular content. The basic message is simple. Responsible state-of-the-art design of new, high technology, prototypes which employ rotating supports proceeds at risk without computerized systems analysis. Tools are there to be used. More are evolving with ever increased sophistication and corroboration with actual hardware performance.
