121 the degrees of freedom will only be assumed on coarse grids. It

MueLu::DefaultNode Node
Class that holds all level-specific information.
Definition: MueLu_Level.hpp:99
Factory for GMG Q2-Q1-Q2 interpolation.
void Build(Level &fineLevel, Level &coarseLevel) const
Build an object with this factory.
void BuildCoarseGrid(Level &fineLevel, Level &coarseLevel) const
void DeclareInput(Level &fineLevel, Level &coarseLevel) const
Specifies the data that this class needs, and the factories that generate that data.
Base class for factories that use two levels (fineLevel and coarseLevel).
Namespace for MueLu classes and methods.
