dft_keywords
|
|
============
|
|
|
|
This module contains the main keywords related to a DFT calculation or RS-DFT calculation, such as:
|
|
|
|
* :option:`dft_keywords exchange_functional`
|
|
* :option:`dft_keywords correlation_functional`
|
|
* :option:`dft_keywords HF_exchange` : only relevent for the :c:func:`rs_ks_scf` program
|
|
|
|
The keyword for the **range separation parameter** :math:`\mu` is the :option:`ao_two_e_erf_ints mu_erf` keyword.
|
|
|
|
The keyword for the type of density used in RS-DFT calculation with a multi-configurational wave function is the :option:`density_for_dft density_for_dft` keyword.
