Function Documentation

bcrsPrint()

void bcrsPrint

(

const Dune::BCRSMatrix< Dune::FieldMatrix< double, 1, 1 > > &

bcrsMatrix

)

Creates a vector of the prolongation matrices (base transformation..) and a vector of the restricted stiffness matrices for each gridlevel

Access to BCRS prolongation matrix from level k to k+1: ProlongationStack<Dune::UGGrid<dim> > ps( gridManager.grid() ); BCRSMatrix<FieldMatrix<double,1,1> > prolongation = ps.prolStack[k];

Access to k times restricted BCRS stiffness matrix with assembled Matrix A: ProlongationStack<Dune::UGGrid<dim> > ps( gridManager.grid() ); MlStack<Dune::UGGrid<dim> > myStack( ps , A ); BCRSMatrix<FieldMatrix<double,1,1> > levelStiff = myStack.levelMatrixStack[k];

We have three classes: ParentalNodes ProlongationStack MlStack
