Engineering programs from Norway
Wheeler's process plant division, New Jersey, USA. AIDS (automated isometric drafting system) has been in full use for the last two years and was originally designed to provide a faster, better and cheaper system than the manual approach. The AIDS system is based on models of plant construction designed by the division. These models provide: 1. A single source reference for all input to the computerized piping system. 2. The means for a complete piping/ instrument system review prior to input. Using the plant model the draftsmen provides the computer with direction, dimensional data and code word information. Any dimensional data is scaled directly from the model and entered on the input form. The information input to the system is processed by a series of computer programs which automatically access pipe specification files containing information regarding the pipe materials to be used. Various other files are accessed; such as dimensions files, equipment files containing co-ordinate data for all equipment and nozzles, and lastly, a commodity file containing rating, facing and descriptive information. Five phases are involved in the production of a piping isometric, the final phase involving the generation of commands to drive a digital plotter. The actual drawing is produced together with an accompanying bill of materials. The plotter is driven offline from commands stored on tape. Several other reports can be produced for use in control. These include piping material requirements from different aspects, e.g. by line number or drawing number or by category such as 'underground' or 'instrument'.
Engineering programs from Norway A catalogue containing brief descriptions of all the engineering programs developed by Det Norske Veritas, Oslo, Norway and A/S Computas has been produced. Entitled 'Engineering Programs 1972', this 180 page catalogue contains abstracts of about 160 programs. Care has been taken to ensure that all the programs have been written in standard Fortran and all have been implemented on a Univac 1108. In addition, some have been run on IBM 360's and Sigma 7's. Information contained in the abstract deals with limitations, source language, number of statements, hardware requirements and the machines implemented on. The abstract is presented in a standard layout. Approximately forty-five of their programs are implemented on the Sigma 7 computer at the Atkins computer centre. This company is licensed to market the programs in the UK. The finite element program system, SESAM-69 is implemented and used at two installations in the UK. The SESAM-69 (Super Element Structural Analysis program Modules) package is intended for use in the shipbuilding industry and provides a program system for dynamic, and static analysis of structures. The system allows for solution by the super-element principle. Up to 800 basic elements may be combined to form one super-element which itself can be handled as a basic element. The system is said to be inexpensive in terms of manpower and computer time required, because of the data generators and the super-element technique. The package consists of I----
Modems go east An order for twenty-one, 2.4 kbaud modems has been placed by the Josef Stefan Institute in Ljubljana, Yugoslavia. The Model 2200/24 modems, manufactured by Racal-Milgo Ltd are intended to provide communication links with a CDC computer. The installation provides services for the University of Ljubljana, the Nuclear Research Institute, the Ljubljana medical centre and three commercial companies.

Plot of structural idealization obtained using the SESAM-69 structure analysis program.
a number of applications programs, any number of which may be combined. The programs can provide an analysis of the following; piping systems, thin shells, solids, threedimensional frames and other problems. Plots of the structural idealization may be obtained to provide a general view of the analysis. Still on the structural analysis theme, many programs are available for dealing with beams, frames and grillages, including on on frame weight optimization. Special hull applications, structural details, vibration, buckling and stability complete the structural aspects of design covered by the programs. A better known package for the naval architect is the PRELIKON system. This integrated program system deals with hydrostatic and other design calculations necessary for ships. Input data for a new hull may be lifted from a body plan, transferred from lines faired by Autokon or arranged as a variation of another described ship. All working modules communicate with a database where hull definition and intermediate results are stored. The type of calculations the modules perform include a hull definition program, hull drawing, hydrostatic particulars~ load distribution and balancing Bonjean tables, stability and others. Several programs for dealing with problems occurring in numerical analysis are available. For example, regression analysis, harmonic analysis and synthesis and linear equation solving. Hydro- and gas-mechanics, waves and ship motion in waves, vibration, machinery, shock and noise control calculations are covered by the next series of programs described in the catalogue. As an example, consider machinery calculations. Programs are available to aid the design of engines, turbines, gears and to deal with vibration and shaft alignment. Sections on propeller design and control, classification rule programs, analysis of recorded measurements, and, lastly, a program on nonlinear temperature fields are also included. Several of the structural analysis and machinery calculation programs are available for timesharing. The programs are available for sale or hire from Det Norske Veritas and A/S Computas who can run them according to the client's detailed requirements.
