ASAS — A Large-Scale, Sophisticated Finite Element Analysis System
Design of ASAS commenced in late 1969 and the first computer bureau version was released in December 1971. The original software was based largely on a research package for elasto-plastic analysis sponsored by the Atomic Weapons Research Establishment, Aldermaston. Although this was a specialist program in terms of its facilities, the design philosophy was quite general so the extension to more catholic use proved relatively straightforward. Now ASAS is a large-scale and sophisticated system which includes capabilities for linear elastic stress and natural frequency analysis of complex structures. In addition, various facilities for dynamic and heat transfer analysis, a substructure (super-element) capability and numerous specialist pre- and post- processor programs are included.
