Detailed Description

template<int dim, int spacedim = dim, typename VectorType = Vector<double>, typename DoFHandlerType = DoFHandler<dim,spacedim>>
class MappingFEField< dim, spacedim, VectorType, DoFHandlerType >::InternalData

Storage for internal data of this mapping. See Mapping::InternalDataBase for an extensive description.

This includes data that is computed once when the object is created (in get_data()) as well as data the class wants to store from between the call to fill_fe_values(), fill_fe_face_values(), or fill_fe_subface_values() until possible later calls from the finite element to functions such as transform(). The latter class of member variables are marked as 'mutable', along with scratch arrays.

◆ unit_tangentials

template<int dim, int spacedim = dim, typename VectorType = Vector<double>, typename DoFHandlerType = DoFHandler<dim,spacedim>>

std::array<std::vector<Tensor<1,dim> >, GeometryInfo<dim>::faces_per_cell *(dim-1)> MappingFEField< dim, spacedim, VectorType, DoFHandlerType >::InternalData::unit_tangentials

Unit tangential vectors. Used for the computation of boundary forms and normal vectors.

This array has (dim-1)*GeometryInfo::faces_per_cell entries. The first GeometryInfo::faces_per_cell contain the vectors in the first tangential direction for each face; the second set of GeometryInfo::faces_per_cell entries contain the vectors in the second tangential direction (only in 3d, since there we have 2 tangential directions per face), etc.

Definition at line 386 of file mapping_fe_field.h.

◆ n_shape_functions

template<int dim, int spacedim = dim, typename VectorType = Vector<double>, typename DoFHandlerType = DoFHandler<dim,spacedim>>

unsigned int MappingFEField< dim, spacedim, VectorType, DoFHandlerType >::InternalData::n_shape_functions

Number of shape functions. If this is a Q1 mapping, then it is simply the number of vertices per cell. However, since also derived classes use this class (e.g. the Mapping_Q() class), the number of shape functions may also be different.

Definition at line 394 of file mapping_fe_field.h.

◆ mask

template<int dim, int spacedim = dim, typename VectorType = Vector<double>, typename DoFHandlerType = DoFHandler<dim,spacedim>>

ComponentMask MappingFEField< dim, spacedim, VectorType, DoFHandlerType >::InternalData::mask

Stores the mask given at construction time. If no mask was specified at construction time, then a default one is used, which makes this class works in the same way of MappingQEulerian(), i.e., the first spacedim components of the FiniteElement are used for the euler_vector and the euler_dh.

If a mask is specified, then it has to match the underlying FiniteElement, and it has to have exactly spacedim non-zero elements, indicating the components (in order) of the FiniteElement which will be used for the euler vector and the euler dof handler.

Definition at line 408 of file mapping_fe_field.h.

◆ covariant

template<int dim, int spacedim = dim, typename VectorType = Vector<double>, typename DoFHandlerType = DoFHandler<dim,spacedim>>

std::vector<DerivativeForm<1,dim, spacedim > > MappingFEField< dim, spacedim, VectorType, DoFHandlerType >::InternalData::covariant

mutable

Tensors of covariant transformation at each of the quadrature points. The matrix stored is the Jacobian * G^{-1}, where G = Jacobian^{t} * Jacobian, is the first fundamental form of the map; if dim=spacedim then it reduces to the transpose of the inverse of the Jacobian matrix, which itself is stored in the contravariant field of this structure.

Computed on each cell.

Definition at line 419 of file mapping_fe_field.h.

◆ contravariant

template<int dim, int spacedim = dim, typename VectorType = Vector<double>, typename DoFHandlerType = DoFHandler<dim,spacedim>>

std::vector< DerivativeForm<1,dim,spacedim> > MappingFEField< dim, spacedim, VectorType, DoFHandlerType >::InternalData::contravariant

mutable

Tensors of contravariant transformation at each of the quadrature points. The contravariant matrix is the Jacobian of the transformation, i.e. \(J_{ij}=dx_i/d\hat x_j\).

Computed on each cell.

mutable

Definition at line 434 of file mapping_fe_field.h.
