Detailed Description

template<int dim, int fe_degree, int n_q_points_1d = fe_degree + 1, int n_components_ = 1, typename Number = double>
class Portable::FEEvaluation< dim, fe_degree, n_q_points_1d, n_components_, Number >

This class provides all the functions necessary to evaluate functions at quadrature points and cell integrations. In functionality, this class is similar to FEValues<dim>.

This class has five template arguments:

Template Parameters

dim	Dimension in which this class is to be used
fe_degree	Degree of the tensor prodict finite element with fe_degree+1 degrees of freedom per coordinate direction
n_q_points_1d	Number of points in the quadrature formular in 1d, defaults to fe_degree+1
n_components	Number of vector components when solving a system of PDEs. If the same operation is applied to several components of a PDE (e.g. a vector Laplace equation), they can be applied simultaneously with one call (and often more efficiently). Defaults to 1
Number	Number format, `double` or `float`. Defaults to `double`.
