Namespace GooseFEM::Element::Quad4::Nodal#

namespace Nodal

nodal quadrature: quadrature points coincide with the nodes.

The order is the same as in the connectivity: 

 3 -- 2
 |    |
 0 -- 1

Functions

inline size_t nip()

Number of integration points:: 

 nip = nne = 4

Returns

unsigned int

inline array_type::tensor<double, 2> xi()

Integration point coordinates (local coordinates).

Returns

Coordinates [nip, ndim], with ndim = 2.

inline array_type::tensor<double, 1> w()

Integration point weights.

Returns

Coordinates [nip].
