Detailed Description

These are the fundamental Operator Solve Interfaces that provide the foundation for all ANAs.

Enumeration Type Documentation

Type of solve measure norm.

For reference we refer to solving a single linear system A*x=b.

Enumerator
SOLVE_MEASURE_ONE 

No solve measure (i.e. same as 1.0)

SOLVE_MEASURE_NORM_RESIDUAL 

Norm of the current residual vector (i.e. ||A*x-b||)

SOLVE_MEASURE_NORM_SOLUTION 

Norm of the current solution vector (i.e. ||x||)

SOLVE_MEASURE_NORM_INIT_RESIDUAL 

Norm of the initial residual vector given a non-zero guess (i.e. ||A*xo-b||)

SOLVE_MEASURE_NORM_RHS 

Norm of the right-hand side (i.e. ||b||)

Definition at line 60 of file Thyra_SolveSupportTypes.hpp.

Solution status.

Enumerator
SOLVE_STATUS_CONVERGED 

The requested solution criteria has likely been achieved.

SOLVE_STATUS_UNCONVERGED 

The requested solution criteria has likely not been achieved.

SOLVE_STATUS_UNKNOWN 

The final solution status is unknown but he solve did not totally fail.

Definition at line 392 of file Thyra_SolveSupportTypes.hpp.

Enum that specifies how a LinearOpWithSolveBase object will be used for solves after it is constructed.

Enumerator
SUPPORT_SOLVE_UNSPECIFIED 

How the output LOWSB object will be useded for solves in unspecified.

SUPPORT_SOLVE_FORWARD_ONLY 

The output LOWSB object will only be used for forward solves.

SUPPORT_SOLVE_TRANSPOSE_ONLY 

The output LOWSB object will only be used for transpose solves.

SUPPORT_SOLVE_FORWARD_AND_TRANSPOSE 

The output LOWSB object will used for forward and transpose solves.

Definition at line 489 of file Thyra_SolveSupportTypes.hpp.

Enum defining the status of a preconditioner object.

Enumerator
PRECONDITIONER_INPUT_TYPE_AS_OPERATOR 

The input preconditioner should just be applied as an operator.

PRECONDITIONER_INPUT_TYPE_AS_MATRIX 

The input preconditioner should viewed as a matrix to be factored then backsolved as a preconditioner.
