Detailed Description

template<class O, class C>
class Dune::Amg::AggregationLevelTransferPolicyCpr< O, C >

A LeveTransferPolicy that used aggregation to construct the coarse level system.

Template Parameters
OThe type of the fine and coarse level operator.
CThe criterion that describes the aggregation procedure.

Member Function Documentation

◆ createCoarseLevelSystem()

template<class O , class C >
void Dune::Amg::AggregationLevelTransferPolicyCpr< O, C >::createCoarseLevelSystem ( const O &  fineOperator)
inlinevirtual

Algebraically creates the coarse level system.

After returning from this function the coarse level operator can be accessed using getCoarseLevelOperator().

Parameters
fineOperatorThe operator of the fine level system.

Implements Dune::Amg::LevelTransferPolicyCpr< O, O >.

◆ moveToFineLevel()

template<class O , class C >
void Dune::Amg::AggregationLevelTransferPolicyCpr< O, C >::moveToFineLevel ( typename FatherType::FineDomainType fineLhs)
inlinevirtual

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]fineLhsThe left hand side of the fine level to update with the coarse level correction.

Implements Dune::Amg::LevelTransferPolicyCpr< O, O >.
