An Object-Oriented Implementation of the Finite Element Method for Coupled problems
Keywords:
coupled problems, piezoelectricity, object-oriented programming, C , command interpreterAbstract
Recent advances in computational hardware allow us to consider solving complex phenomena (e.g., coupled problems, large non linearities, optimization, etc.). Complexity of problems to be analyzed is constantly increasing due to cu"ent industrial demands that pose severe constraints to software developers. Object-oriented programming has emerged as a solution to manage complexity. In this paper, we describe aspects in the development of a finite element pro gram written in C++. Particular aspects of the fonnulation, as the concepts of partition and tools for the decomposition of the problem into several sub-parts, are introduced. Examples illustrating applications to the solution of piezoelectric motor modeling and of shape optimization are shown.
