Member Function Documentation

void Trilinos_Util::VbrMatrixGallery::ComputeDiffBetweenStartingAndExactSolutionsVbr ( double & residual )

Computes the 2-norm of the difference between the starting solution and the exact solution for the VBR problem.

void Trilinos_Util::VbrMatrixGallery::ComputeResidualVbr ( double & residual )

Computes the 2-norm of the residual for the VBR problem.

void Trilinos_Util::VbrMatrixGallery::CreateBlockMap ( void ) [protected]

void Trilinos_Util::VbrMatrixGallery::CreateVbrExactSolution ( void ) [protected]

Creates the exact solution for a Epetra_VbrMatrix.

void Trilinos_Util::VbrMatrixGallery::CreateVbrMatrix ( void )

void Trilinos_Util::VbrMatrixGallery::CreateVbrRHS ( ) [protected]

Create the RHS corresponding to the desired exact solution for the Vbr problem.

void Trilinos_Util::VbrMatrixGallery::CreateVbrStartingSolution ( ) [protected]

Creates the starting solution for Vbr.

const Epetra_BlockMap * Trilinos_Util::VbrMatrixGallery::GetBlockMap ( )

Returns a pointer the internally stored BlockMap.

const Epetra_BlockMap & Trilinos_Util::VbrMatrixGallery::GetBlockMapRef ( )

Epetra_Vector * Trilinos_Util::VbrMatrixGallery::GetVbrExactSolution ( )

Returns a pointer to the selected Vbr exact solution.

Epetra_LinearProblem * Trilinos_Util::VbrMatrixGallery::GetVbrLinearProblem ( )

Returns a pointer to Epetra_LinearProblem for VBR.

Epetra_VbrMatrix * Trilinos_Util::VbrMatrixGallery::GetVbrMatrix ( )

Returns a VbrMatrix, starting from the CsrMatrix.

Epetra_VbrMatrix * Trilinos_Util::VbrMatrixGallery::GetVbrMatrix ( const int NumPDEEqns )

Returns a VbrMatrix, starting from the CsrMatrix.
Returns a VbrMatrix, starting from the CsrMatrix. This vbr matrix is formally equivalent to the CrsMatrix returned by GetMatrix(). However, each node of the CrsMatrix is replicated num_PDE_eqns times (this value is passed in input, or set via Set("num pde eqns",IntValue)).

Epetra_VbrMatrix & Trilinos_Util::VbrMatrixGallery::GetVbrMatrixRef ( )

Epetra_Vector * Trilinos_Util::VbrMatrixGallery::GetVbrRHS ( )

Returns a pointer to the RHS for the selected Vbr exact solution.
Returns a pointer to the RHS corresponding to the selected exact solution to the linear systems defined by the Epetra_VbrMatrix.
