✦ Synopsis

Making a ®nite element code easier to maintain is achieved by further modularizing it. Due to its two levels of modularity (of procedures and data), object-oriented programming is the method of choice. Its potential is investigated in two bottlenecks of ®nite element programming where so far it has not proved signi®cantly more successful than classical Fortran programming. The ®rst of these is the lack of adequate data structures between the analysis speci®cations and the basic objects of the ®nite element method, like the element and the node. This is solved by de®ning two classes of objects, namely problem and domain, with clearly dierentiated speci®cations. The second gap deals with solving linear equation systems. Introducing an intermediate class UnassembledMatrix allows alternative storage/solving schemes to be implemented in a very ¯exible manner.

## Abstract The finite element method is by its nature very modular. Object oriented programming enables full advantage to be taken of this modularity. This makes for safer and easier programming, and extending or modifying object oriented programs is very straightforward. The paper describes an ob

Systems of non-linear equations as they arise when analysing various physical phenomena and technological processes by the implicit Finite Element Method (FEM) are commonly solved by the Newton-Raphson method. The modelling of sheet metal forming processes is one example of highly non-linear problem
