◆ AdditionalData()

template<typename Number, typename MemorySpace = ::MemorySpace::Host>

LinearAlgebra::TpetraWrappers::PreconditionBlockJacobi< Number, MemorySpace >::AdditionalData::AdditionalData	(	const int	n_local_parts = 1,
		const double	omega = 1.,
		const int	block_overlap = 0,
		const int	n_sweeps = 1 )

Constructor.

Set the parameters to be used in the preconditioner. The defaults yield a textbook Jacobi preconditioner.

Parameters

n_local_parts	The number of blocks per processor.
omega	The damping factor for the relaxation.
block_overlap	Amount of overlap between blocks
n_sweeps	Number of relaxation sweeps per call to vmult or Tvmult
