| bool | is_mapping_q1_data |
| unsigned int | n_shape_functions |
Storage for internal data of d-linear transformation.
Definition at line 110 of file mapping_q1.h.
| MappingQ1< dim, spacedim >::InternalData::InternalData | ( | const unsigned int | n_shape_functions ) |
Constructor. Pass the number of shape functions.
Reimplemented in MappingQ< dim, spacedim >::InternalData.
| double MappingQ1< dim, spacedim >::InternalData::shape | ( | const unsigned int | qpoint, |
| const unsigned int | shape_nr | ||
| ) | const |
Shape function at quadrature point. Shape functions are in tensor product order, so vertices must be reordered to obtain transformation.
| double& MappingQ1< dim, spacedim >::InternalData::shape | ( | const unsigned int | qpoint, |
| const unsigned int | shape_nr | ||
| ) |
Shape function at quadrature point. See above.
| Tensor<1,dim> MappingQ1< dim, spacedim >::InternalData::derivative | ( | const unsigned int | qpoint, |
| const unsigned int | shape_nr | ||
| ) | const |
Gradient of shape function in quadrature point. See above.
| Tensor<1,dim>& MappingQ1< dim, spacedim >::InternalData::derivative | ( | const unsigned int | qpoint, |
| const unsigned int | shape_nr | ||
| ) |
Gradient of shape function in quadrature point. See above.
| Tensor<2,dim> MappingQ1< dim, spacedim >::InternalData::second_derivative | ( | const unsigned int | qpoint, |
| const unsigned int | shape_nr | ||
| ) | const |
Second derivative of shape function in quadrature point. See above.
| Tensor<2,dim>& MappingQ1< dim, spacedim >::InternalData::second_derivative | ( | const unsigned int | qpoint, |
| const unsigned int | shape_nr | ||
| ) |
Second derivative of shape function in quadrature point. See above.
| virtual std::size_t MappingQ1< dim, spacedim >::InternalData::memory_consumption | ( | ) | const [virtual] |
Return an estimate (in bytes) or the memory consumption of this object.
Reimplemented from Mapping< dim, spacedim >::InternalDataBase.
Reimplemented in MappingQ< dim, spacedim >::InternalData.
| std::vector<double> MappingQ1< dim, spacedim >::InternalData::shape_values |
Values of shape functions. Access by function shape.
Computed once.
Definition at line 183 of file mapping_q1.h.
| std::vector<Tensor<1,dim> > MappingQ1< dim, spacedim >::InternalData::shape_derivatives |
Values of shape function derivatives. Access by function derivative.
Computed once.
Definition at line 192 of file mapping_q1.h.
| std::vector<Tensor<2,dim> > MappingQ1< dim, spacedim >::InternalData::shape_second_derivatives |
Values of shape function second derivatives. Access by function second_derivative.
Computed once.
Definition at line 202 of file mapping_q1.h.
| std::vector<Tensor<2,spacedim> > MappingQ1< dim, spacedim >::InternalData::covariant |
Tensors of covariant transformation at each of the quadrature points. The matrix stored is the inverse of the Jacobian matrix, which itself is stored in the contravariant field of this structure.
Computed on each cell.
Definition at line 217 of file mapping_q1.h.
| std::vector<Tensor<2,spacedim> > MappingQ1< dim, spacedim >::InternalData::contravariant |
Tensors of contravariant transformation at each of the quadrature points. The contravariant matrix is the Jacobian of the transformation, i.e.
.
Computed on each cell.
Definition at line 245 of file mapping_q1.h.
| std::vector<std::vector<Tensor<1,dim> > > MappingQ1< dim, spacedim >::InternalData::unit_tangentials |
Unit tangential vectors. Used for the computation of boundary forms and normal vectors.
This vector has (dim-1)*GeometryInfofaces_per_cell entries. The first GeometryInfo<dim>::faces_per_cell contain the vectors in the first tangential direction for each face; the second set of GeometryInfo<dim>::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.
Filled once.
Definition at line 269 of file mapping_q1.h.
| std::vector<std::vector<Tensor<1,spacedim> > > MappingQ1< dim, spacedim >::InternalData::aux |
Auxiliary vectors for internal use.
Definition at line 274 of file mapping_q1.h.
| std::vector<Point<spacedim> > MappingQ1< dim, spacedim >::InternalData::mapping_support_points |
Stores the support points of the mapping shape functions on the cell_of_current_support_points.
Definition at line 281 of file mapping_q1.h.
| Triangulation<dim,spacedim>::cell_iterator MappingQ1< dim, spacedim >::InternalData::cell_of_current_support_points |
Stores the cell of which the mapping_support_points are stored.
Definition at line 288 of file mapping_q1.h.
| bool MappingQ1< dim, spacedim >::InternalData::is_mapping_q1_data |
Default value of this flag is true. If *this is an object of a derived class, this flag is set to false.
Definition at line 297 of file mapping_q1.h.
| unsigned int MappingQ1< dim, spacedim >::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.
