Constructor & Destructor Documentation

AdditionalData()

template<int dim>

PETScWrappers::PreconditionBDDC< dim >::AdditionalData::AdditionalData	(	const bool	use_vertices = true,
		const bool	use_edges = false,
		const bool	use_faces = false,
		const bool	symmetric = false,
		const std::vector< Point< dim > >	coords = {}
	)

Constructor. Note that BDDC offers a lot more options to set than what is exposed here.

Member Data Documentation

use_vertices

template<int dim>

bool PETScWrappers::PreconditionBDDC< dim >::AdditionalData::use_vertices

This flag sets the use of degrees of freedom in the vertices of the subdomains as primal variables for the creation of the coarse space.

Definition at line 1016 of file petsc_precondition.h.

use_edges

template<int dim>

bool PETScWrappers::PreconditionBDDC< dim >::AdditionalData::use_edges

This flag sets the use of degrees of freedom in the edges of the subdomain as primal variables for the creation of the coarse space. Continuity is actually imposed at the edge average.

Definition at line 1023 of file petsc_precondition.h.

use_faces

template<int dim>

bool PETScWrappers::PreconditionBDDC< dim >::AdditionalData::use_faces

This flag sets the use of degrees of freedom in the faces of the subdomain as primal variables for the creation of the coarse space. Continuity is actually imposed at the face average.

Definition at line 1030 of file petsc_precondition.h.

symmetric

template<int dim>

bool PETScWrappers::PreconditionBDDC< dim >::AdditionalData::symmetric

Set whether the matrix is symmetric or not.

Definition at line 1035 of file petsc_precondition.h.

coords

template<int dim>

std::vector<Point<dim> > PETScWrappers::PreconditionBDDC< dim >::AdditionalData::coords

Set the location of each DoF. This helps in improving the definition of the vertices for unstructured meshes.
