Variable Documentation

const unsigned int libMesh::QuadratureRules::num_rules = 5

The number of quadrature rules that are defined (INVALD_Q_RULE excluded). You might have to update this if you add a new one!

Definition at line 46 of file quadrature_rules.h.

const unsigned int libMesh::QuadratureRules::num_valid_elem_rules = 3

The number of valid quadrature rules for numerical integration over geometric entities.

Definition at line 61 of file quadrature_rules.h.

const QuadratureType libMesh::QuadratureRules::valid_elem_rules[]

Initial value:

 {QGAUSS,
                                             QSIMPSON,
                                             QTRAP}

The types of quadrature rules that may be used for numerical integration over geometric entities.
