Detailed Description
class Dune::Amg::LevelTransferPolicy< FO, CO >
Abstract base class for transfer between levels and creation of the coarse level system.
- Template Parameters
-
FO The type of the linear operator of the finel level system. Has to be derived from AssembledLinearOperator. CO The type of the linear operator of the coarse level system. Has to be derived from AssembledLinearOperator.
Member Function Documentation
◆ createCoarseLevelSystem()
|
pure virtual |
Algebraically creates the coarse level system.
After returning from this function the coarse level operator can be accessed using getCoarseLevelOperator().
- Parameters
-
fineOperator The operator of the fine level system.
Implemented in Dune::Amg::AggregationLevelTransferPolicy< O, C >.
Referenced by Dune::Amg::TwoLevelMethod< FO, CSP, S >::TwoLevelMethod().
◆ getCoarseLevelLhs()
|
inline |
Get the coarse level left hand side.
- Returns
- The coarse level leftt hand side.
References Dune::Amg::LevelTransferPolicy< FO, CO >::lhs_.
◆ getCoarseLevelOperator()
|
inline |
Get the coarse level operator.
- Returns
- A shared pointer to the coarse level system.
References Dune::Amg::LevelTransferPolicy< FO, CO >::operator_.
◆ getCoarseLevelRhs()
|
inline |
Get the coarse level right hand side.
- Returns
- The coarse level right hand side.
References Dune::Amg::LevelTransferPolicy< FO, CO >::rhs_.
◆ moveToCoarseLevel()
|
pure virtual |
Transfers the data to the coarse level.
Restricts the residual to the right hand side of the coarse level system and initialies the left hand side of the coarse level system. These can afterwards be accessed usinf getCoarseLevelRhs() and getCoarseLevelLhs().
- Parameters
-
fineDefect The current residual of the fine level system.
◆ moveToFineLevel()
|
pure virtual |
Updates the fine level linear system after the correction of the coarse levels system.
After returning from this function the coarse level correction will have been added to fine level system.
- Parameters
-
[in,out] fineLhs The left hand side of the fine level to update with the coarse level correction.
Implemented in Dune::Amg::AggregationLevelTransferPolicy< O, C >.
