template<int dim>

MeshWorker::WorkerObjects::IntegrationWorker< dim >::IntegrationWorker ( )

inline

Constructor, which sets the UpdateFlags flags to their default values.

References MeshWorker::WorkerObjects::IntegrationWorker< dim >::bdry_flags, MeshWorker::WorkerObjects::IntegrationWorker< dim >::cell_flags, MeshWorker::WorkerObjects::IntegrationWorker< dim >::face_flags, and MeshWorker::WorkerObjects::IntegrationWorker< dim >::ngbr_flags.

Member Function Documentation

template<int dim>

void MeshWorker::WorkerObjects::IntegrationWorker< dim >::add_selector ( const std::string &  name, bool  values, bool  gradients, bool  hessians, bool  cell, bool  bdry, bool  face  )

inline

Add a FEVector name as it is stored in FEVectors to some or all selectors.

template<int dim>

void MeshWorker::WorkerObjects::IntegrationWorker< dim >::add_update_flags ( const UpdateFlags  flags, bool  cell = true, bool  bdry = true, bool  face = true, bool  ngbr = true  )

inline

Add additional UpdateFlags flags.

References MeshWorker::WorkerObjects::IntegrationWorker< dim >::bdry_flags, MeshWorker::WorkerObjects::IntegrationWorker< dim >::cell_flags, MeshWorker::WorkerObjects::IntegrationWorker< dim >::face_flags, and MeshWorker::WorkerObjects::IntegrationWorker< dim >::ngbr_flags.

template<int dim>

void MeshWorker::WorkerObjects::IntegrationWorker< dim >::initialize_gauss_quadrature ( unsigned int  n_cell_points, unsigned int  n_bdry_points, unsigned int  n_face_points  )

inline

Assign n-point Gauss quadratures to each of the quadrature rules.

Here, a size of zero points means that no loop over these grid entities should be performed.

References MeshWorker::WorkerObjects::IntegrationWorker< dim >::bdry_quadrature, MeshWorker::WorkerObjects::IntegrationWorker< dim >::cell_quadrature, dim, and MeshWorker::WorkerObjects::IntegrationWorker< dim >::face_quadrature.

template<int dim>

void MeshWorker::WorkerObjects::IntegrationWorker< dim >::initialize_selectors ( const VectorSelector &  cs, const VectorSelector &  bs, const VectorSelector &  fs  )

inline

Initialize the VectorSelector objects cell_selector, bdry_selector, and face_selector.

If no selectors are used, then values for all named FEVector vectors in FEVectors will be computed in all quadrature points.

This function will also add UpdateFlags to the flags stored in this class.
