ESF_NINTER = [integer]
Default: ESF_NINTER = 15 

Description: ESF_NINTER sets the maximum number of interpolation steps for the electronic structure factor (ESF_SPLINES).


If the threshold set by ESF_CONV has not been reached within ESF_NINTER iterations VASP will print a warning about insufficient convergence.
