Member Function Documentation

◆ Clone()

virtual TPZIntPoints* TPZIntCube3D::Clone ( ) const
inlinevirtual

Make a clone of the related cubature rule.

Implements TPZIntPoints.

Definition at line 307 of file pzquad.h.

◆ Dimension()

virtual int TPZIntCube3D::Dimension ( ) const
inlinevirtual

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

Implements TPZIntPoints.

Definition at line 298 of file pzquad.h.

References TPZInt1d::Dim.

◆ GetMaxOrder()

virtual int TPZIntCube3D::GetMaxOrder ( ) const
inlinevirtual

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.

TPZIntPoints method that returns a coherent maxime order to work It is necessary because now can to be computed rule with integration points up to one thousand.

Reimplemented from TPZIntPoints.
