A parallel fictitious domain multigrid preconditioner for the solution of Poisson’s equation in complex geometries

A parallel multilevel preconditioner based on domain decomposition and fictitious domain methods has been presented for the solution of the Poisson equation in complicated geometries. Rectangular blocks with matching grids on interfaces on a structured rectangular mesh have been used for the decompo...
