Detailed Description
class Dune::Fem::QuadratureRulesFactory< FieldImp, dim >
quadrature implementation based on the standard DUNE quadratures
Though a factory by name, this is a quadrature implementation using the standard quadratures from DUNE grid to generate a list of quadrature points.

Member Function Documentation
◆ addQuadraturePoint()
|
inlineprotectedinherited |
Adds a point-weight pair to the quadrature.
This method allows derived classes to add quadrature points (and their respective weights) to the list. This mehtod should only be used within the constructor of the derived class.

obtain the identifier of the integration point list
The identifier of an integration point list must be globally unique. Even integration point lists for different dimensions must have different identifiers.
- Note
- Quadratures are considered distinct if they differ in one of the following points: geometry type, order, dimension or implementation.
- Returns
- globally unique identifier of the integration point list

◆ nop()
|
inlineinherited |
obtain the number of integration points
- Returns
- number of integration points within this list
Referenced by Dune::Fem::IntegrationPointListImp< FieldImp, dim >::point().
◆ order()
|
inlinevirtual |
obtain order of the integration point list
The order of a quadrature is the maximal polynomial degree that is guaranteed to be integrated exactly by the quadrature.
In case of an integration point list, the definition of this value is left to the implementor.
- Returns
- the order of the integration point list

◆ point()
|
inlineinherited |
obtain coordinates of i-th integration point
This method returns a reference to the coordinates of the i-th integration point for 0 <= i < nop(). The integration point is given in local coordinates, i.e., coordinates with respect to the reference element.
- Parameters
-
[in] i number of the integration point, 0 <= i < nop()
- Returns
- reference to i-th integration point

◆ weight()
|
inlineinherited |
obtain weight of i-th integration point
This method returns the weight of the i-th integration point for 0 <= i < nop() within the quadrature.
- Note
- The integration point can be obtained via the point() method.
- The quadrature weights sum up to the volume of the reference element.
- Parameters
-
[in] i number of the integration point, 0 <= i < nop()
- Returns
- weight of the i-th integration point
