Field Documentation

d_derShapes

std::vector<std::vector<double> > fe::QuadData::d_derShapes

Derivatives of shape functions at the quad point.

On the reference element this is dN/dξ. After getQuadDatas it is physical dN/dx. Size is number of nodes; d_derShapes[i][j] is derivative of N_i in coordinate j.

d_detJ

double fe::QuadData::d_detJ

Determinant of the Jacobian of the map from reference element to the element.

Definition at line 60 of file quadData.h.

d_J

std::vector<std::vector<double> > fe::QuadData::d_J

Jacobian of the map from reference element to the element.

In 1-d, size is 1, 2-d size is \( 2\times 2\), and in 3-d size is \( 3\times 3\).

d_p

util::Point fe::QuadData::d_p

d_shapes

std::vector<double> fe::QuadData::d_shapes

Value of shape functions at quad point p.

Size will be the number of vertices the element has. E.g. for triangle element shapes will have three entries.
