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,
std::vector< std::vector< std::vector< Tensor< 1, spacedim, Number >>>> &  gradients,
std::vector< std::vector< std::vector< Tensor< 2, spacedim, Number >>>> &  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
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.

Reimplemented in MeshWorker::VectorData< VectorType, dim, spacedim >.

◆ mg_fill()

template<int dim, int spacedim = dim, typename Number = double>
virtual void MeshWorker::VectorDataBase< dim, spacedim, Number >::mg_fill ( std::vector< std::vector< std::vector< Number >>> &  values,
std::vector< std::vector< std::vector< Tensor< 1, spacedim, Number >>>> &  gradients,
std::vector< std::vector< std::vector< Tensor< 2, spacedim, Number >>>> &  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.

Reimplemented in MeshWorker::VectorData< VectorType, dim, spacedim >.
