GEM

GEM (G eneric E ngineering Analysis M odel) is a completed European Community funded ESPRIT project managed by NAFEMS. The aim was to enable engineering analysis methods such as finite element analysis of solids or fluids to be used more effectively within the design and analysis process. The methodology behind GEM was to integrate software applications in the context of engineering analysis in an open, ISO-STEP-compliant way. These applications included coverage of product analysis modellers, mesh generators, analysis packages and/or modules, and post-processors.

R0043 ,   Bohms, H M, et al,   The GEM Modelling Methodology, 1995.

This report was prepared as part of the GEM project. The report contains information on how to specify the GEM modelling methodology as a progress step during the development of the project.

R0048 ,   Bohms, H M, et al,   Report on Solution of Users’ Problems, 1997.

This report was prepared as part of the GEM project The report deals with the solutions to two particular problems to demonstrate how various engineering software packages interface with the developed GEM model. The contributions were from Dornier and Fiat.

R0044 ,   Goult, R, Leal, D, and Helpenstein, H,   A Guide to Shape Models & Relevant Resource Parts in STEP,1995.

This report gives an introduction to those parts of STEP which are of particular relevance to the GEM project. In particular, it includes those parts concerned with the representation of the shape of a product and those dealing with finite element analysis. It contains a lot of detailed information, although in view of software progress it may no longer be up to date.

R0047 ,   Helpenstein, H, et al,   Improving Integration in Engineering Analysis, 1997.

This is a report from the GEM project. It describes the scope of the GEM project and the business architecture (i.e. how GEM was defined and implemented) and gives applications which demonstrate the GEM concept. Details include data types and their usage. Two industrial examples are summarised, then a discussion on the opportunities for future implementation of GEM by software vendors and industrial companies is given.

R0042 ,   Le Gouez, J M, Boheas, M A, and Miles, C J,   Data Requirements for Analysis Modelling, 1995.

This is a report from the GEM project. It describes the problem domains and analysis disciplines that are part of the GEM project, and explores the data requirements for generic modelling and simulation of field problems in industry. It contains a lot of information relevant to the actual data required to analysis modelling, including a survey of currently available codes, although this data is continually being superceded.

R0045,   Miles, G, and Trace, S R,   A Guide to Implementation Techniques, 1995.

This is a report from the GEM project. It describes the concept of data transfer systems (STEP, etc.) which are the central issue in a project like GEM where there are many different analysis codes over many locations. It contains lots of information relevant to the implementation techniques adopted during the project.

R0046 ,   Zilly, F,   Specification of Demonstration Problems, 1995.

This is a report from the GEM project, and describes a variety of example problems supplied by the project partners.
