Description: ESF_NINTER sets the number of interpolation steps for the tricubic spline interpolation in ACFDT/RPA calculations.
ESF_NINTER sets the number of tricubic interpolation steps in ACFDT/RPA calculations. This tag is used in conjunction with ESF_SPLINES and ESF_CONV. 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_NINTER 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. |
