Detailed Description

template<typename VectorType, int dim, int spacedim = dim>
class MeshWorker::VectorData< VectorType, dim, spacedim >

Based on VectorSelector, this is the class that implements the function VectorDataBase::fill() for a certain type of vector, using AnyData to identify vectors by name.

Member Function Documentation

initialize() [1/2]

template<typename VectorType , int dim, int spacedim = dim>

void MeshWorker::VectorData< VectorType, dim, spacedim >::initialize

(

const AnyData &

)

Initialize with an object of named vectors.

initialize() [2/2]

template<typename VectorType , int dim, int spacedim = dim>

void MeshWorker::VectorData< VectorType, dim, spacedim >::initialize	(	const VectorType *	,
		const std::string &	name
	)

Initialize with a single vector 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<typename VectorType , int dim, int spacedim = dim>

virtual void MeshWorker::VectorData< VectorType, dim, spacedim >::fill ( std::vector< std::vector< std::vector< typename VectorType::value_type > > > &  values, std::vector< std::vector< std::vector< Tensor< 1, spacedim, typename VectorType::value_type > > > > &  gradients, std::vector< std::vector< std::vector< Tensor< 2, spacedim, typename VectorType::value_type > > > > &  hessians, const FEValuesBase< dim, spacedim > &  fe, const std::vector< types::global_dof_index > &  index, const unsigned int  component, const unsigned int  n_comp, const unsigned int  start, const unsigned int  size  ) 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.

mg_fill()

template<typename VectorType , int dim, int spacedim = dim>

virtual void MeshWorker::VectorData< VectorType, dim, spacedim >::mg_fill ( std::vector< std::vector< std::vector< typename VectorType::value_type > > > &  values, std::vector< std::vector< std::vector< Tensor< 1, spacedim, typename VectorType::value_type > > > > &  gradients, std::vector< std::vector< std::vector< Tensor< 2, spacedim, typename VectorType::value_type > > > > &  hessians, const FEValuesBase< dim, spacedim > &  fe, const unsigned int  level, const std::vector< types::global_dof_index > &  index, 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.
