LRTolScheme

Section Linear Response::SCF in LR calculations
Type integer
Default tol_adaptive

The scheme used to adjust the tolerance of the solver during the SCF iteration. For kdotp and magnetic em_resp modes, or whenever HamiltonianVariation = V_ext_only, the scheme is set to tol_fixed, and this variable is ignored.

Options:

tol_fixed:
The solver tolerance is fixed for all the iterations; this improves convergence but increases the computational cost
tol_adaptive:
The tolerance is increased according to the level of convergence of the SCF.
tol_linear:
The tolerance decreases linearly for the first LRTolIterWindow iterations.
tol_exp:
The tolerance decreases exponentially for the first LRTolIterWindow iterations.
