Constructor & Destructor Documentation

◆ PartialReassembler()

template<class Assembler >
Dumux::PartialReassembler< Assembler >::PartialReassembler ( const Assembler &  assembler)
inline
Parameters
assemblerthe assembler

Member Function Documentation

◆ computeColors()

template<class Assembler >
void Dumux::PartialReassembler< Assembler >::computeColors ( const Assembler &  assembler,
const std::vector< Scalar > &  distanceFromLastLinearization,
Scalar  threshold 
)
inline

The following approach is used:

  • Set all elements to 'green'
  • Mark all elements as 'red' which exhibit an relative error above the tolerance
  • Mark all neighbors of 'red' elements also 'red'
Parameters
assemblerthe assembler
distanceFromLastLinearizationThe distance from the last linearization
thresholdReassemble only if the distance from the last linearization is above this value.
