inlinevirtual

Make a clone of the related cubature rule.

Implements TPZIntPoints.

Definition at line 464 of file pzquad.h.

◆ Dimension()

virtual int TPZIntPrism3D::Dimension ( ) const

inlinevirtual

Returns the dimension of the master element related for the cubature rule.

Implements TPZIntPoints.

◆ GetMaxOrder()

int TPZIntPrism3D::GetMaxOrder ( ) const

virtual

Returns the minimum order to integrate polinomials exactly for all implemented cubature rules.

Note: To get real maxime order for especific rule call GetRealMaxOrder(), but for Gauss rule 1D the implementation can to compute a cubature rule up to on hundred order.
