bse_types Module Reference

The BSE environment: the settings of the &BSE section and the state a GW path prepares for the solver core (window, energies, window-sized RI slabs, inverse dielectric matrix). More...

Data Types
type	bse_env_type
	Settings of the &BSE section (read_bse_section, re-read by prepare_bse_env, normalised in place by adapt_BSE_input_params) and the state prepare_bse_env fills for bse_solve. More...

Functions/Subroutines
subroutine, public	bse_env_release (bse_env)
	Releases the state a GW path prepared and nullifies the QS pointers; the settings stay, including the section pointer and the two lists into the input tree, since prepare_bse_env re-reads them from the section when a later energy evaluation on the same environment runs the BSE again. Safe on an unprepared environment.

subroutine, public bse_types::bse_env_release

(

type(bse_env_type), intent(inout)

bse_env

)

Releases the state a GW path prepared and nullifies the QS pointers; the settings stay, including the section pointer and the two lists into the input tree, since prepare_bse_env re-reads them from the section when a later energy evaluation on the same environment runs the BSE again. Safe on an unprepared environment.

Parameters

bse_env

the environment whose prepared state is released
