RESUMO

In Engineering many physical phenomena are modeled using differential equations. The finite element method is very efficient to solve these equations numerically. Many applications lead to very large problems, whose solution requires specialized methods. The most recent tool for solving large scale problems is the parallel processing. This tool is used together with the substructuring technique, which consists in splitting the domain of the problem, generating a coarse mesh. The coarse mesh is assembled into a system of equations named the reduced system. This system is solved by using the pre-conditionedconjugate gradient. This work includes two parts: the first one is the implementation of substructuring using the object oriented programming paradigm. The second part is devoted to the construction of a pre-conditioner resulting ftom the modification of the shape functions on the contours of the substructures into hierarchical basis functions
