The paper describes the latest version of the GIFTS SYSTEM Graphics Oriented Interactive Finite Element Package for Time-Sharing, due for release at the end of March 1976. The paper gives a description of the program modules available in the GIFTS library and the options available within its framework. Examples are given to demonstrate the use of GIFTS in design-oriented applications. Some performance measurements are included. Amongst the GIFTS features described are Automatic model and load generation Generation and display of higher order elements Display of model, loads, boundary conditions, deflections and stresses Suitability for use as a pre- and post-processor for large batch programs Static analysis capabilities for trusses, frames, membranes, plates and shells Vibrational mode computation for complex structures Transient response analysis using either direct integration or a model analysis approach Substructuring and constrained substructuring Mixed boundary conditions Thermal stress. Three examples have been chosen for inclusion in the paper. They illustrate some of the more important aspects of the GIFTS III system. These examples include the analysis of a three-dimensional framework, vibrational mode computation of an aircraft wing and the analysis, using substructures, of a bulk-ore carrier.
