| Popis: | Both the explicit Taylor-Galerkin scheme, based on a finite-element formulation, and the multifrontal method are specially adapted to process unstructured problems. The explicit Taylor-Galerkin scheme is designed for fluid dynamics computations on unstructured grids and produces an irregular sparse matrix that will be factorized using a multifrontal method. The presentation of this new method also involves the use of vectorization and micro- and multitasking techniques on the IBM 3090. The calculation of a Karman-Vortex-Street is used as a test problem for this method. |
