Detailed Description

template<typename T>
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 for each cell. Note that the squares of the cell indicator is stored. To compute the global error estimate sum up all values and take the square root.

Assumptions and limitations:

• Assumes that LFSU is / finite element space and LFSV is a finite element space (one value per cell).
• Convection term is ignored (but reaction term is included)
