ESF CONV: Difference between revisions

Latest revision as of 14:08, 18 December 2024

ESF_CONV = [real]
Default: ESF_CONV = 0.01

Description: Sets the convergence criterion for ESF_SPLINES, i.e., the threshold for the energy difference between two interpolations (in eV).

If the energy between two interpolated k-point grids is less than ESF_CONV the calculation is considered to be converged. If the threshold has not been reached within ESF_NINTER iterations VASP will print a warning about insufficient convergence.
