Finite Element Model Data Checkout with Interactive Graphics

Features of an interactive graphics computer program which provides structural analysts with a method of inspecting and correcting the input data for a large structural analysis computer program are discussed. The structure defined by the input data is displayed on a high-speed graphics display and can be viewed in dynamic rotation, studied at a large scale, tested for correct definition, and corrected when errors are detected. The program has been found to be a great aid in correcting and verifying input data and has considerably reduced the time and cost of data preparation.
