The Finite Element Method is a powerful numerical method for solving partial differential equations. It is widely used in many fields in civil, mechanical, biomechanical, aerospace, and electrical engineering. Using this method the engineer can simulate the thermo-chemo-hydro mechanical behaviour of solids, fluids, and structures. In many cases, these calculations are frequently very time demanding, especially when the underlying models are non-linear and three-dimensional. Typical examples are the simvlation of crack growth which requires up to several weeks of computing time, and most of the problems in multiphysics. The typical trouble in these cases is ill-conditioning of governing equations. Since several of these simulations are required to evaluate a numerical model or structural design, it is necessary to speed up the computations. An attractive way to achieve this speed up is the use of parallel algorithms.
