Introduction

This doxygen collection contains support software for implementing and using the Fundamental Thyra ANA Operator Solve Interfaces.

Software

• Composite Subclasses
  • Thyra::DefaultDiagonalLinearOpWithSolve implements the Thyra::LinearOpWithSolveBase interface for diagonal linear operators.

• Testing Support
  • Thyra::LinearOpWithSolveTester is a unit testing class for Thyra::LinearOpWithSolveBase and can be used to check the solve accuracy of any linear solve.

Examples

• Templated FFT examples

• ANA Linear Solver Adapters for Amesos: This software defines the implementation of the extended interfaces Thyra::LinearOpWithSolveBase and Thyra::LinearOpWithSolveFactoryBase in terms of Amesos_BaseSolver implementations. These adapters allow a client to take any Epetra_RowMatrix object embedded in a Thyra::EpetraLinearOp object and immediately use to to define a direct linear solver.

• ANA Linear Solver Adapters for AztecOO: This software defines the implementation of the extended interfaces Thyra::LinearOpWithSolveBase and Thyra::LinearOpWithSolveFactoryBase in terms of the AztecOO class. These adapters allow a client to take any Epetra_RowMatrix object embedded in a Thyra::EpetraLinearOp object and immediately use to to define an iterative linear solver such as GMRES or CG.

• Stratimikos: Unified Wrappers for Thyra Linear Solver and Preconditioner Adapters: Stratimikos contains neatly packaged access to all of the Thyra linear solver and preconditioner wrappers. Currently, these allow the creation of linear solvers for nearly any Epetra_RowMatrix object. However, the Belos implementation allows for the arbitrary implemention of the linear operators and vector spaces.
