QuadratureType
Defines an enum for currently available quadrature rules.
const unsigned int _beta
ElemType
Defines an enum for geometric element types.
The libMesh namespace provides an interface to certain functionality in the library.
QJacobi(const unsigned int _dim, const Order _order=INVALID_ORDER, const unsigned int a=1, const unsigned int b=0)
Constructor.
const unsigned int _alpha
void init(triangulateio &t)
Initializes the fields of t to NULL/0 as necessary.
Order
defines an enum for polynomial orders.
Definition: enum_order.h:32
The QBase class provides the basic functionality from which various quadrature rules can be derived...
