This publication describes an alternative methodology for finite element programming based on object-oriented techniques. The concepts of object-oriented programming are outlined and it is explained, how this new paradigm facilitates design, implementation and support of large programming systems. Because the knowledge of object-oriented programs is not dispersed in the actual code, but rather localized in structures, the causal knowledge, meta knowledge and constraints may be integrated in a uniform manner. Control structures separate the external level ('what') from the internal ('how') by encapsulating the actual implementation. As programming language C++ is used.
Up till now several object-oriented finite element frameworks have been presented which are partially extendable. However, the extendibility is limited to a few specific directions, e.g. the introduction of new element types or solving strategies. Much less support is available for task control, creation of new material models, configurable field variable types or extensions of the analysis model. No framework is available which is especially designed to cover the problems encountered when dealing with geotechnical engineering. IMAGINE tries to close these gaps.
