void x_to_molecule ()

void molecule_to_x ()

Ref< PointGroup > initial_pg_

int print_molecule_when_changed_

The KeyVal constructor.

molecule

A Molecule object. There is no default.

coor

A MolecularCoor object that describes the coordinates. If this is not given cartesian coordinates will be used. For convenience, two keywords needed by the MolecularCoor object are automatically provided: natom3 and matrixkit.

value_accuracy

Sets the accuracy to which values are computed. The default is 1.0e-6 atomic units.

gradient_accuracy

Sets the accuracy to which gradients are computed. The default is 1.0e-6 atomic units.

hessian_accuracy

Sets the accuracy to which hessians are computed. The default is 1.0e-4 atomic units.

print_molecule_when_changed

If true, then whenever the molecule's coordinates are updated they will be printed. The default is true.

checkpoint

If true, then this object will be checkpointed during its evaluation. Not all implementations of MolecularEnergy support checkpointing. The default is false.

checkpoint_file

Specifies the name of the file into which this object will be checkpointed. Default is '<inpubasename>.ckpt', where '<inputbasename>' is the name of the input file without '.in'.

checkpoint_freq

Specifies how often this object to be checkpointed. Only matters for objects which are computed iteratively. Default is 1.

An optimizer can call change coordinates periodically to give the function an opportunity to change its coordinate system.

A return value of 0 means the coordinates were not changed. Otherwise, a transform object to the new coordinate system is return. The function object applies the transform to any objects it contains. This will obsolete the function data.

Reimplemented from sc::Function.

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::Function.

Reimplemented in sc::CLKS, sc::HSOSKS, sc::UKS, sc::MBPT2, sc::MBPT2_R12, sc::PsiWavefunction, sc::PsiSCF, sc::PsiCCSD, sc::PsiCCSD_T, sc::CLHF, sc::CLSCF, sc::HSOSHF, sc::HSOSSCF, sc::SCF, sc::UHF, sc::UnrestrictedSCF, sc::OneBodyWavefunction, and sc::Wavefunction.

These are passed gradients and hessian in cartesian coordinates.

The gradient and hessian in internal coordinates are computed.
