Abstract | A data base concept is implemented in the development of a symbolic manipulation program. The program - AIT (Analysis Interpretive Treatise) is designed to carry processes in Structural analysis by the matrix and finite element methods. The program consists of a central unit and various satellite processors. The central unit includes a controller and a centralized data bank, a The data, bank ;is accessible to all satellite processors, The control acting like a central administrator, receives commands from users. Each command specifies a sequence of processes to be executed together with names of data units to be used. The control, after receiving command, orders the respective processor to perform the required process using the data available in the data bank. A convention of symbolic free-format input is employed to identify individual processes, and data units. This constitutes a symbolic language by which the users can communicate with the program, Processors are self-contained individual modules, each performing a specific function. The modularity structure and its modification conveniences can prevent the program from remaining unnecessarily obsolete, In the present AIT version, three groups of processes are available: 1) Matrix manipulation and operations. 2) Finite element processes, e,g., element stiffness assembling, static condensation, sub structuring, eigenvalue solution. 3) Generation of characteristic arrays of a finite element mesh, Several meshes (domains) can be generated in the same environment, thus permitting multidomain interactions. Finally, complete documentation of AIT program including a user's manual is given. Several examples are used to illustrate the program versatility, and the effectiveness of the symbolic language, |
