Detailed Description

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

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

Member Function Documentation

template<class VECTOR , int dim, int spacedim = dim>
void MeshWorker::VectorData< VECTOR, dim, spacedim >::initialize ( const NamedData< VECTOR * > &   )

Initialize with a NamedData 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.
template<class VECTOR , int dim, int spacedim = dim>
void MeshWorker::VectorData< VECTOR, dim, spacedim >::initialize ( const VECTOR *  ,
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.

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:
valuesis the vector filled with the values of the finite element function in the quadrature points.
gradientsis the vector filled with the derivatives of the finite element function in the quadrature points.
hessiansis the vector filled with the second derivatives of the finite element function in the quadrature points.
feis the FEValuesBase object which is used to compute the function values. Its UpdateFlags must have been set appropriately.
indexis 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.
componentis the first index in values, gradients and hessians entered in this function.
n_compis the number of components to be filled.
startis the first index of this block in indices, or zero if no base elements are used.
sizeis the number of dofs per cell of the current element or base element.
