<span style="font-family: Arial; font-size:12pt">Goodmorning qe community,<br>
I created an interface metal/semic by using virtual nanolab; when I come to check my structure with xcrysden I notice that, when vacuum is added enlarging the corresponding CELL_PARAMETERS component, all my atoms move along that direction, effectively expanding
the cell instead of introducing vacuum layers.<br>
Where do I mess up? I thought the system is such that fixed celldm () and ATOMIC_POSITIONS all atoms should not move anymore.<br>
Thanks, have a nice day.<br>
