Digital Simulation/ Continuous Systems

In particular, recent advances in design computerization have enabled entire design layouts to be accomplished at a computer terminal. Interactive graphic displays allow the designer to produce a &dquo;drawing&dquo; on a cathode ray tube (CRT) and store the design information in memory. Copiers are available that can produce a hard copy of the displayed graphics; commercially accessible plotters can be used to produce accurate, full-scale layouts. New software permits data-base storage and access to standard components and subassemblies, in addition to the analytical and computation capabilities generally required in an engineering design. This entire area of design, where an engineer/designer interacts with a computer input device, controls various systems, accesses storage, and utilizes stored computational schemes, is the basis for computer-aided design. lhe design process itself is computer-based. The design, with all its supporting information, becomes part of the accessible data base.
