Detailed Description
template<typename B, typename CU, typename CV>
class Dune::PDELab::LocalAssemblerInterface< B, CU, CV >
class Dune::PDELab::LocalAssemblerInterface< B, CU, CV >
The local assembler which provides the engines that drive the global assembler.
The local assembler provides engines for the standard operations of the grid operator. This includes setting up the pattern, computing the residual and the jacobian matrix.
It also provides a standard interface which may be used by implementations of time stepping methods.
