Abstract

The parallel implementation of domain decomposition methods remains difficult for the finite element software used in computational modelling of material forming processes. In a first part, this paper shows the adequacy of the Object Oriented Programming (O.O.P.) for the architecture of a software used for the simulation of forging processes. This is demonstrated by giving a basic architecture of the finite element software written in C++. Then the contribution of the O.O.P. is demonstrated for the domain decomposition method as the Schur complement one. Finally, an algorithm for load balancing is proposed that takes into account the non-linearity due to the elasto-plastic behaviour.
