 As a first step, we perform a static self-consistent Kohn–Sham density functional theory (DFT) calculation to obtain the electronic energy. Our model system is the L-alanine crystal, consisting of 13 atoms per molecule and 4 molecules in the unit cell.
-The example input and output files are in ... The calculations were performed with CP2K version 2025.1.
 ===== Input files =====
-We first look at the input files required for this calculation, which are:

 The file ''Lalanine.out'' contains the main output of the job. The file ''Lalanine-RESTART.wfn'' contains the final Kohn–Sham wavefunctions from the calculation. Files of the form ''Lalanine-RESTART.wfn.bak-<n>'' store the wavefunctions obtained from the $n$-th previous SCF step; in this case, ''Lalanine-RESTART.wfn.bak-1'' contains the wavefunctions from the last SCF step.
