quadrature weights

Question

This is a follow-up to the quadrature points question: How can I get the quadrature weights of Quad on the mesh?

Quad = VectorFunctionSpace(mesh, "Quadrature", 2)

Answer 1

The quadrature schemes are handled by FFC. For a given shape, degree and scheme you can get the points and weights as follows:

from ffc.quadrature_schemes import create_quadrature

shape = "tetrahedron"
degree = 2
scheme="default"

(points, weights) = create_quadrature(shape, degree, scheme)
