✦ Synopsis

One of the major reasons why finite element codes are difficult to keep clean and maintainable is that operations involving nodal information (and in particular, boundary conditions) show up in many sections of the programs and in many different contexts. The matter is further complicated by the inadequacy of the unstructured procedural programming approach promoted by the Fortran language. This article addresses the management of linear constraints, and does so from an object-oriented programming viewpoint. Emphasis is laid on both the model design and the practical programming details.

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

## 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
