GLFEM - Generic linking of finite element based models
Overview
Background & policy context:
The project was about ensuring cost efficiency in air transport. The focus was on reduction of aircraft acquisition costs. Innovative solutions and technologies combined with a competitive supply chain, were to result in: (i) lower lead time and (ii) reduced costs of the aircraft from design to production.
Objectives:
The objectives of the GLFEM project were the development of:
- Advanced methods and computational tools in the fields of structural analysis;
- Concepts and methodologies for efficient multi-site product development in support of the extended enterprise.
The project contributed to the mentioned costs/lead times reduction and a more competitive supply chain, by enabling companies to seamlessly couple their analysis capabilities.
Methodology:
This coupling was done by analysis model interfacing and by providing a definable combination of accuracy, ease of use and intellectual property protection.
The project delivered advanced methods and computational tools for structural analysis. More specifically, the deliverables enabled the coupling of finite element based structural analysis models of different origin and modelling fidelity, with no interaction during initial model creation. The coupling was generic (linear, non-linear, static, dynamic, shell-to-shell, solid-to-shell) and automatic. It was applied to 4 different industrial use cases.
Several approaches were pursued in competition, making use of a common finite element research package. The best of the class for a given application type was implemented in a commercial grade finite element code. Models could then be created independently by different partners at different locations, concurrently, with a minimum of communication needed. This resulted in an efficient multi site product development methodology in support of the extended enterprise.
