The base class for all preconditioners based on Trilinos sparse matrices.
Definition at line 77 of file trilinos_precondition.h.
Declare the type for container size.
Definition at line 83 of file trilinos_precondition.h.
| TrilinosWrappers::PreconditionBase::PreconditionBase | ( | ) |
Constructor. Does not do anything. The initialize function of the derived classes will have to create the preconditioner from a given sparse matrix.
Definition at line 37 of file trilinos_precondition.cc.
| TrilinosWrappers::PreconditionBase::PreconditionBase | ( | const PreconditionBase & | base | ) |
Copy constructor.
Definition at line 46 of file trilinos_precondition.cc.
| TrilinosWrappers::PreconditionBase::~PreconditionBase | ( | ) |
Destructor.
Definition at line 58 of file trilinos_precondition.cc.
| void TrilinosWrappers::PreconditionBase::clear | ( | ) |
Destroys the preconditioner, leaving an object like just after having called the constructor.
Definition at line 63 of file trilinos_precondition.cc.

Apply the preconditioner.
Reimplemented in TrilinosWrappers::PreconditionIdentity.

Apply the transpose preconditioner.
Reimplemented in TrilinosWrappers::PreconditionIdentity.
|

Apply the preconditioner on deal.II data structures instead of the ones provided in the Trilinos wrapper class.
Reimplemented in TrilinosWrappers::PreconditionIdentity.

Apply the transpose preconditioner on deal.II data structures instead of the ones provided in the Trilinos wrapper class.
Reimplemented in TrilinosWrappers::PreconditionIdentity.

virtual |
Apply the preconditioner on deal.II parallel data structures instead of the ones provided in the Trilinos wrapper class.

virtual |
Apply the transpose preconditioner on deal.II parallel data structures instead of the ones provided in the Trilinos wrapper class.
| Epetra_Operator& TrilinosWrappers::PreconditionBase::trilinos_operator | ( | ) | const |
Return a reference to the underlaying Trilinos Epetra_Operator. So you can use the preconditioner with unwrapped Trilinos solver.
Calling this function from an uninitialized object will cause an exception.

This is a pointer to the preconditioner object that is used when applying the preconditioner.

Internal communication pattern in case the matrix needs to be copied from deal.II format.
