Detailed Description

template<int dim>
struct aspect::Introspection< dim >::Quadratures

A structure that contains appropriate quadrature formulas for the finite elements that correspond to each of the variables in this problem, as well as for the complete system (the system variable).

If there are compositional fields, they are all discretized with the same polynomial degree and, consequently, we only need a single formula.

The quadrature formulas provided here are chosen such that the compute integrals with sufficient accuracy. For hypercube cells, this means in particular that they are of Gauss type with a number of Gauss points per coordinate direction that is one larger than the polynomial degree of the finite element per direction. For example, when using quadratic elements for the velocity, the corresponding quadrature formula will have three Gauss points per direction. If the mesh is based on triangles or tetrahedra, the quadrature formula is not of tensor-product Gauss type, but the corresponding analog for simplex cells.
