Métodos de Descomposición de Dominio en Mecánica de Fluidos Computacional (Ph.D talk)
Abstract
[Slides, oral defense]
The main purpose of the present thesis work is the efficient solution
of large scale problems arising in Computational Fluid Dynamics
challenge problems, the proposition of new ideas in preconditioning
techniques, the implementation of such ideas in a parallel
multiphysics C++ code using the message passing paradigm via MPI/PETSc
libraries and its evaluation on a Beowulf class cluster. These topics
are presented in the first part of this work. The second part is
devoted to the application of the algorithm proposed in the first part
to the solution of more general/complex problems like the wave
absorption on fictitious boundaries and the resolution of
fluid-structure problems in the supersonic regime of a compressible
fluid flow.
