Detailed Description

template<int dim>
class FE_RT_Bubbles< dim >

This class implements a curl-enhanced Raviart-Thomas elements, conforming with H^div space. The node functionals are defined as point values in Gauss-Lobatto points. These elements generate vector fields with normal components continuous between mesh cells. The purpose of this finite element is in localizing the interactions between degrees of freedom around the nodes when an appropriate quadrature rule is used, leading to a block-diagonal mass matrix (even with full-tensor coefficient).

The elements are defined through enrichment of classical Raviart-Thomas elements with extra curls, so that the H^div conformity is preserved, and the total number of degrees of freedom of FE_RT_Bubbles of order k is equal to the number of DoFs in dim copies of FE_Q of order k.

Note: Unlike Raviart-Thomas, the lowest possible order for this enhanced finite element is 1, i.e. \(k \ge 1\).

The matching pressure space for FE_RT_Bubbles of order k is FE_DGQ of order k-1. With the exact integration, this pair yields \((k+1)\)-st order of convergence in \(L_2\)-norm for a vector variable and \(k\)-th order in \(L_2\)-norm for a scalar one (same as \(BDM_k \times P_{k-1}\)).

For this enhanced Raviart-Thomas element, the node values are not cell and face moments with respect to certain polynomials, but the values in Gauss-Lobatto quadrature points. The nodal values on edges (faces in 3D) are evaluated first, according to the natural ordering of the edges (faces) of a cell. The interior degrees of freedom are evaluated last.

For an RT-Bubbles element of degree k, we choose (k+1)^dim-1 Gauss-Lobatto points on each face. These points are ordered lexicographically with respect to the orientation of the face. In the interior of the cells, the values are computed using an anisotropic Gauss-Lobatto formula for integration. The mass matrix assembled with the use of this same quadrature rule, is block diagonal with blocks corresponding to quadrature points. See "Higher order multipoint flux mixed finite element methods on quadrilaterals and hexahedra" for more details.

The elements of degree \(k=3\) in 2D and \(k=2\) in 3D are shown in the figures below (filled arrows indicate DoFs for which continuity across the edges (faces in 3D) is required).

Left - \(2D,\,k=3\), right - \(3D,\,k=2\).

◆ clone()

template<int dim>

std::unique_ptr< FiniteElement< dim, dim > > FE_RT_Bubbles< dim >::clone ( ) const

overridevirtual

A sort of virtual copy constructor, this function returns a copy of the finite element object. Derived classes need to override the function here in this base class and return an object of the same type as the derived class.

Some places in the library, for example the constructors of FESystem as well as the hp::FECollection class, need to make copies of finite elements without knowing their exact type. They do so through this function.

◆ convert_generalized_support_point_values_to_dof_values()

template<int dim>

void FE_RT_Bubbles< dim >::convert_generalized_support_point_values_to_dof_values	(	const std::vector< Vector< double >> &	support_point_values,
		std::vector< double > &	nodal_values
	)		const

overridevirtual

Given the values of a function \(f(\mathbf x)\) at the (generalized) support points of the reference cell, this function then computes what the nodal values of the element are, i.e., \(\Psi_i[f]\), where \(\Psi_i\) are the node functionals of the element (see also Node values or node functionals). The values \(\Psi_i[f]\) are then the expansion coefficients for the shape functions of the finite element function that interpolates the given function \(f(x)\), i.e., \( f_h(\mathbf x) = \sum_i \Psi_i[f] \varphi_i(\mathbf x) \) is the finite element interpolant of \(f\) with the current element. The operation described here is used, for example, in the FETools::compute_node_matrix() function.

In more detail, let us assume that the generalized support points (see this glossary entry ) of the current element are \(\hat{\mathbf x}_i\) and that the node functionals associated with the current element are \(\Psi_i[\cdot]\). Then, the fact that the element is based on generalized support points, implies that if we apply \(\Psi_i\) to a (possibly vector-valued) finite element function \(\varphi\), the result must have the form \(\Psi_i[\varphi] = f_i(\varphi(\hat{\mathbf x}_i))\) – in other words, the value of the node functional \(\Psi_i\) applied to \(\varphi\) only depends on the values of \(\varphi\) at \(\hat{\mathbf x}_i\) and not on values anywhere else, or integrals of \(\varphi\), or any other kind of information.

The exact form of \(f_i\) depends on the element. For example, for scalar Lagrange elements, we have that in fact \(\Psi_i[\varphi] = \varphi(\hat{\mathbf x}_i)\). If you combine multiple scalar Lagrange elements via an FESystem object, then \(\Psi_i[\varphi] = \varphi(\hat{\mathbf x}_i)_{c(i)}\) where \(c(i)\) is the result of the FiniteElement::system_to_component_index() function's return value's first component. In these two cases, \(f_i\) is therefore simply the identity (in the scalar case) or a function that selects a particular vector component of its argument. On the other hand, for Raviart-Thomas elements, one would have that \(f_i(\mathbf y) = \mathbf y \cdot \mathbf n_i\) where \(\mathbf n_i\) is the normal vector of the face at which the shape function is defined.

Given all of this, what this function does is the following: If you input a list of values of a function \(\varphi\) at all generalized support points (where each value is in fact a vector of values with as many components as the element has), then this function returns a vector of values obtained by applying the node functionals to these values. In other words, if you pass in \(\{\varphi(\hat{\mathbf x}_i)\}_{i=0}^{N-1}\) then you will get out a vector \(\{\Psi[\varphi]\}_{i=0}^{N-1}\) where \(N\) equals dofs_per_cell.

Parameters

[in]	support_point_values	An array of size `dofs_per_cell` (which equals the number of points the get_generalized_support_points() function will return) where each element is a vector with as many entries as the element has vector components. This array should contain the values of a function at the generalized support points of the current element.
[out]	nodal_values	An array of size `dofs_per_cell` that contains the node functionals of the element applied to the given function.

Note: It is safe to call this function for (transformed) values on the real cell only for elements with trivial MappingType. For all other elements (for example for H(curl), or H(div) conforming elements) vector values have to be transformed to the reference cell first.; Given what the function is supposed to do, the function clearly can only work for elements that actually implement (generalized) support points. Elements that do not have generalized support points – e.g., elements whose nodal functionals evaluate integrals or moments of functions (such as FE_Q_Hierarchical) – can in general not make sense of the operation that is required for this function. They consequently may not implement it.
