Dune::Fem::AuxiliaryDofs< GridPart, Mapper > Class Template Reference

In parallel computations the dofs of a discrete function are made up by all primary dofs. For technical reasons some dofs exists on multiply processes but are only primary on exactly one process. Dofs on processes that are not primary are called auxiliary. More...

Detailed Description

template<class GridPart, class Mapper>
class Dune::Fem::AuxiliaryDofs< GridPart, Mapper >

In parallel computations the dofs of a discrete function are made up by all primary dofs. For technical reasons some dofs exists on multiply processes but are only primary on exactly one process. Dofs on processes that are not primary are called auxiliary.
