| void | PsiCorrWavefunction::compute () |
| sc::PsiSCF::PsiSCF | ( | const Ref< KeyVal > & | ) |
The KeyVal constructor uses all keywords of PsiWavefunction class and the following additional keywords:
guess_wavefunctionThis specifies the initial guess for the solution to the SCF equations. This can be either a OneBodyWavefunction object or the name of file that contains the saved state of a OneBodyWavefunction object. By default the one-electron hamiltonian will be diagonalized to obtain the initial guess.
| void sc::PsiSCF::import_occupations | ( | const Ref< OneBodyWavefunction > & | obwfn | ) |
imports occupations from obwfn.
Will throw if docc_ and socc_ had been initialized and do not match obwfn.
| void sc::PsiSCF::obsolete | ( | ) | [virtual] |
Marks all results as being out of date.
Any subsequent access to results will cause Compute::compute() to be called.
Reimplemented from sc::PsiWavefunction.
| void sc::PsiSCF::save_data_state | ( | StateOut & | ) | [virtual] |
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::PsiWavefunction.
| void sc::PsiSCF::symmetry_changed | ( | ) | [virtual] |
Call this if you have changed the molecular symmetry of the molecule contained by this MolecularEnergy.
Reimplemented from sc::PsiWavefunction.
