Cut-off energy for plane wave basis set in eV.
All plane-waves with a kinetic-energy smaller than 
are included in the basis set: i.e.
Mind: The number of plane wave differs for each k-point. This leads
to a superior basis-set for V-E calculations (volume energy calculations)
with a 'constant energy cut-off'. If the volume is increased the total number
of plane waves changes very smoothly.
The criterion 
(i.e. same basis set for each k-point)
would lead to a rougher E-V curve.
Starting from version VASP 3.2 the POTCAR files contains a default ENMAX (and ENMIN) line, therefore it is no longer necessary to specify ENCUT in the INCAR file. Of course the value in the INCAR file overwrites the default in the POTCAR file. For POTCAR files with more than one species the maximum cutoff (ENMAX or ENMIN) value is used for the calculation (see below).
