Member Function Documentation

template<typename Scalar >

bool Hermes::Hermes2D::DiscreteProblemSelectiveAssembler< Scalar >::prepare_sparse_structure	(	SparseMatrix< Scalar > *	mat,
		Vector< Scalar > *	rhs,
		std::vector< SpaceSharedPtr< Scalar > >	spaces,
		Traverse::State **&	states,
		unsigned int &	num_states
	)

Preassembling. Precalculate matrix sparse structure. If force_diagonal_block == true, then (zero) matrix antries are created in diagonal blocks even if corresponding matrix weak forms do not exist. This is useful if the matrix is later to be merged with a matrix that has nonzeros in these blocks. The Table serves for optional weighting of matrix blocks in systems. Returns false if there are no states to assemble.

Todo:: do not get the assembly list again if the element was not changed.
