Exempel på hur man kan använda PRECONDITIONER i en mening

• A multigrid method with an intentionally reduced tolerance can be used as an efficient preconditioner for an external iterative solver, e.
• The simplest version of FETI with no preconditioner (or only a diagonal preconditioner) in the substructure is scalable with the number of substructures but the condition number grows polynomially with the number of elements per substructure.
• Since the BDD preconditioner involves the solution of Neumann problems on all subdomain, it is a member of the Neumann–Neumann class of methods, so named because they solve a Neumann problem on both sides of the interface between subdomains.
• The extension to more subdomains is straightforward, but using this method as stated as a preconditioner for the Schur complement system is not scalable with the number of subdomains; hence the need for a global coarse solve.
• In mathematics, the Neumann–Dirichlet method is a domain decomposition preconditioner which involves solving Neumann boundary value problem on one subdomain and Dirichlet boundary value problem on another, adjacent across the interface between the subdomains.
• For performances, the Schur complement method is combined with preconditioning, at least a diagonal preconditioner.
