Abstract:We present a biomechanical application of our parallel finite element model for coupled problems in solid mechanics. This programming framework provides a very lean and flexible interface, which allows to realize time-dependent nonlinear simulations. In this context, a special variant of a stabilized local Gauß-Seidel preconditioner is introduced, which can be successfully employed to large scale computations. Finally, the efficiency of the implemented algorithm is shown by a numerical example considering the axial compression of a L4-L5 motion segment of the spine. (© 2005 WILEY-VCH Verlag GmbH & Co.
