Abstract:
The analysis of large-scale nonlinear shell problems asks for parallel simulation approaches. One crucial part of effi- cient and well scalable parallel FE-simulations is the solver for the system of equations. Due to the inherent suitability for parallelization one is verymuch directed towards preconditioned iterative solvers. However thin-walled-structures discretized byfinite elements lead to ill-conditioned system matrices and therefore performance of iterative solvers is generallypoor. This...     »
