Detailed Description

IntegralCCA provides an SC client for CCA IntegralEvaluator components.


Constructor & Destructor Documentation

The KeyVal constructor.

This constructor is used when the framework is embedded. The following keywords are read:

evaluator_factory

This gives the symbol name of a CCA IntegralEvaluatorFactory component. This symbol name should also appear in the cca-load argument. The default is MPQC.IntegralEvaluatorFactory.

integral_package

If the default MPQC.IntegralEvaluatorFactory is used, then this option may be used to specify the integrals package to use (intv3, cints, or libint2). The default is intv3.

molecule
This gives a molecule object, it is required.

Member Function Documentation

Ref<OneBodyInt> sc::IntegralCCA::dipole ( const Ref< DipoleData > &  = 0) [virtual]

Return a OneBodyInt that computes electric dipole moment integrals, i.e.

integrals of the $e (\mathbf{r}-\mathbf{C})$ operator. Multiply by -1 to obtain electronic electric dipole integrals. The canonical order of integrals in a set is x, y, z.

Implements sc::Integral.

Return a OneBodyInt that computes the electric field integrals dotted with a given vector.

Implements sc::Integral.

Return a TwoBodyInt that computes electron repulsion integrals.

This TwoBodyInt will produce a set of integrals described by TwoBodyIntDescrERI.

Reimplemented from sc::Integral.

Return a 2-body evaluator that computes two-electron integrals specific to linear R12 methods.

According to the convention in the literature, "g" stands for electron repulsion integral, "r" for the integral of r12 operator, and "t" for the commutator integrals. This TwoBodyInt will produce a set of integrals described by TwoBodyIntDescrR12. Implementation for this kind of TwoBodyInt is optional.

NumCenters specifies the number of centers that carry basis functions. Valid values are 4, 3, and 2.

Reimplemented from sc::Integral.

Return a CartesianIter object.

The caller is responsible for freeing the object.

Implements sc::Integral.

Return a RedundantCartesianIter object.

The caller is responsible for freeing the object.

Implements sc::Integral.

Return a RedundantCartesianSubIter object.

The caller is responsible for freeing the object.

Implements sc::Integral.

SphericalTransformIter* sc::IntegralCCA::new_spherical_transform_iter ( int  l,
int  inv = 0,
int  subl = -1 
) [virtual]

Return a SphericalTransformIter object.

This factory must have been initialized with a basis set whose maximum angular momentum is greater than or equal to l. The caller is responsible for freeing the object.

Implements sc::Integral.

Return a OneBodyInt that computes the nuclear repulsion integrals.

Charges from the atoms on center one are used. If center two is not identical to center one, then the charges on center two are included as well.

Implements sc::Integral.

Return a OneBodyInt that computes $\bar{p}\times V\bar{p}$, where $V$ is the nuclear potential.

This is different than most other one body integrals, in that each entry in the integral buffer is a vector of three integrals.

Reimplemented from sc::Integral.

Return a OneBodyInt that computes $\bar{p}\cdot V\bar{p}$, where $V$ is the nuclear potential.

Reimplemented from sc::Integral.

Return a OneBodyInt that computes the integrals for interactions with point charges.

Implements sc::Integral.

Ref<OneBodyInt> sc::IntegralCCA::quadrupole ( const Ref< DipoleData > &  = 0) [virtual]

Return a OneBodyInt that computes electric quadrupole moment integrals, i.e.

integrals of the $e (\mathbf{r}-\mathbf{C}) \otimes (\mathbf{r}-\mathbf{C})$ operator. Multiply by -1 to obtain electronic electric quadrupole integrals. The canonical order of integrals in a set is x^2, xy, xz, y^2, yz, z^2.

Implements sc::Integral.

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.

This must be implemented by the derived class if the class has data.

Reimplemented from sc::Integral.

const SphericalTransform* sc::IntegralCCA::spherical_transform ( int  l,
int  inv = 0,
int  subl = -1 
) [virtual]

Return a SphericalTransform object.

This factory must have been initialized with a basis set whose maximum angular momentum is greater than or equal to l. The pointer is only valid while this Integral object is valid.

Implements sc::Integral.
