Description: ESF_CONV sets the convergence criterion for the tricubic spline interpolation in ACFDT/RPA calculations.
ESF_CONV sets the convergence criterion in the tricubic spline interpolation of the RPA correlation energy. This tag is used in conjunction with ESF_SPLINES and ESF_NITER. If ESF_SPLINES=T is set the RPA correlation energy is interpolated to finer k-point meshes using a tricubic spline interpolation.[1] 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_NITER iterations vasp will print an insufficient convergence warning to screen.
| Tip: This method works for metals and insulators. |
| Warning: Remove WAVEDER before running the job and avoid setting LOPTICS. |
