Detailed Description

template<class GO>
class Dune::PDELab::ISTLBackend_NOVLP_CG_SSORk< GO >

Nonoverlapping parallel CG solver preconditioned by block SSOR.

Template Parameters

GO	The type of the grid operator used for the spatial discretization. This class will be used to adjust the discretization matrix. and extract the trial grid function space.
