Detailed Description

template<typename T>
class Ifpack_AdditiveSchwarz< T >

Ifpack_AdditiveSchwarz: a class to define Additive Schwarz preconditioners of Epetra_RowMatrix's.

Class Ifpack_AdditiveSchwarz enables the construction of Additive Schwarz (one-level overlapping domain decomposition) preconditioners, for a given Epetra_RowMatrix. Ifpack_AdditiveSchwarz is derived from Ifpack_Preconditioner, itself derived from Epetra_Operator. An application of the Additive Schwarz preconditioner can be obtained by calling method ApplyInverse().

One-level overlapping domain decomposition preconditioners use local solvers, of Dirichlet type. This means that the inverse of the local matrix (with minimal or wider overlap) is applied to the residual to be preconditioned.

The preconditioner can be written as:

$P_{AS}^{-1} = \sum_{i=1}^M P_i A_i^{-1} R_i ,$

where $M$ is the number of subdomains (that is, the number of processors in the computation), $R_i$ is an operator that restricts the global vector to the vector lying on subdomain $i$ , $P_i$ is the prolongator operator, and

$A_i = R_i A P_i.$

The construction of Schwarz preconditioners is mainly composed by two steps:

definition of the restriction and prolongation operator and . If minimal overlap is chosen, their implementation is trivial, will return all the local components. For wider overlaps, instead, Epetra_Import and Epetra_Export will be used to import/export data. The user must provide both the matrix to be preconditioned (which is suppose to have minimal-overlap) and the matrix with wider overlap.
definition of a technique to apply the inverse of . To solve on each subdomain, the user can adopt any class, derived from Ifpack_Preconditioner. This can be easily accomplished, as Ifpack_AdditiveSchwarz is templated with the solver for each subdomain.

The local matrix $A_i$ can be filtered, to eliminate singletons, and reordered. At the present time, RCM and METIS can be used to reorder the local matrix.

The complete list of supported parameters is reported in page ifp_params.

virtual

If set true, transpose of this operator will be applied (not implemented).

This flag allows the transpose of the given operator to be used

implicitly.

Parameters

UseTranspose_in - (In) If true, multiply by the transpose of operator, otherwise just use operator.
