update_state()

subroutine siesta_state::update_state	(	logical, intent(in)	lprint,
		real (dp), intent(in)	fsq_total,
		real (dp), intent(in)	ftol

Update the SIESTA state.

Adds the perturbation to the field. This is called before taking the next step.

Parameters

[in]	lprint	Controls screen output.
[in]	fsq_total	Total force residual.
[in]	ftol	Force residual tolarance.
