The file EIGENVALUE contains the Kohn-Sham-eigenvalues for all k-points, at the end of the simulation. For dynamic simulation (IBRION=0) the eigenvalues on the file are usually that one predicted for the next step: i.e. the file is compatible with CONTCAR. For static calculations and relaxations (IBRION=-1,1,2) the eigenvalues are the solution of KS-equations for the last step.

*Mind*: For dynamic simulations (IBRION=0) the EIGENVAL file
contains predicted wavefunctions compatible with CONTCAR.
If you want to use the eigenvalues for additional calculations,
first copy CONTCAR to POSCAR and make another
static (ISTART=1; NSW=0) continuation run with ICHARG=1.
