Member Function Documentation

◆ initialize()

template<int dim, int spacedim = dim, typename Number = double>

void MeshWorker::VectorDataBase< dim, spacedim, Number >::initialize ( const AnyData & )

Initialize with a AnyData object and cache the indices in the VectorSelector base class.

Note: Make sure the VectorSelector base class was filled with reasonable data before calling this function.

◆ fill()

template<int dim, int spacedim = dim, typename Number = double>

virtual void MeshWorker::VectorDataBase< dim, spacedim, Number >::fill	(	std::vector< std::vector< std::vector< Number >>> &	values,

	)		const

virtual

The only function added to VectorSelector is an abstract virtual function implemented in the derived class template and called by IntegrationInfo.

Depending on the selections made in our base class, this fills the first three arguments with the local data of the finite element functions. It is usually called either for the whole FESystem, or for each base element separately.

Parameters

values	is the vector filled with the values of the finite element function in the quadrature points.
gradients	is the vector filled with the derivatives of the finite element function in the quadrature points.
hessians	is the vector filled with the second derivatives of the finite element function in the quadrature points.
fe	is the FEValuesBase object which is used to compute the function values. Its UpdateFlags must have been set appropriately.
index	is the local index vector. If `fe` refers to base elements of the system, this vector should be sorted by block and the arguments `start` and `size` below specify the subset of `indices` used.
component	is the first index in `values`, `gradients` and `hessians` entered in this function.
n_comp	is the number of components to be filled.
start	is the first index of this block in `indices`, or zero if no base elements are used.
size	is the number of dofs per cell of the current element or base element.

		const unsigned int	component,
		const unsigned int	n_comp,
		const unsigned int	start,
		const unsigned int	size
	)		const

virtual

Fill the local data vector from level vectors. Performs exactly what the other fill() does, but uses the cell level to access a single level out of a hierarchy of level vectors, instead of a global data vector on the active cells.

◆ add()

void MeshWorker::VectorSelector::add	(	const std::string &	name,
		const bool	values = `true`,
		const bool	gradients = `false`,
		const bool	hessians = `false`
	)

inlineinherited

Add a vector to the selection of finite element functions. The arguments are the name of the vector and indicators, which information is to be extracted from the vector. The name refers to an entry in a AnyData object, which will be identified by initialize(). The three bool parameters indicate, whether values, gradients and Hessians of the finite element function are to be computed on each cell or face.
