class Dune::PDELab::ConvectionDiffusionDG_ErrorIndicator< T >
a local operator for residual-based error estimation
A call to residual() of a grid operator space will assemble the quantity \(\eta_T^2\) for each cell. Note that the squares of the cell indicator \(\eta_T\) is stored. To compute the global error estimate sum up all values and take the square root.
Assumptions and limitations:
- Assumes that LFSU is \(P_1\)/ \(Q_1\) finite element space and LFSV is a \(P_0\) finite element space (one value per cell).
- Convection term is ignored (but reaction term is included)
- Template Parameters
