[GUESS]: Initial Guess Settings for Self-consistent Field Calculations

[GUESS] Defaults
Keyword Default Description
type huckel Method for generating the initial guess.
file (none) Name of the JSON checkpoint file.
file2 (none) Name of the second JSON checkpoint file.
save_mol False Option to save a JSON file after the job is completed.
continue_geom False Specifies whether to use molecular geometry from a JSON file.
swapmo (none) MO indices that you want to swap. Pairs should be given—for example, 1,10 swaps MO 1 and MO 10. If an index does not form a complete pair, it will be ignored. For example, 1,10,15 will only swap MO1 and MO10.

      • hcore: Hcore guess.
      • molden: Read orbitals from a Molden file.
      • json: Load data from a JSON file.
  • file: Specify the guess orbital or data file.
    • Details: Provide the name or absolute path to the Molden or JSON file.
  • save_mol: Save complete data to a JSON file.
    • Options:
      • True: Save the complete calculation data to a JSON file.
      • False: Do not save data. (Default)
  • continue_geom: Choose the structure for calculations.
    • Options:
      • True: Use the structure saved in the JSON file.
      • False: Use the input structure. (Default)
