[Pw_forum] periodic boundary condition

[mohaddeseh abbasnejad]

Dear all,

I want to calculate the total energy of Si atom using CASINO without
imposing periodic boundary conditions.
At the first step, I should prepare a file containing wavefunction's
cofficients by QE code.
I know that for calculating the total energy of an atom, I have to use
supercell, which it also imposes periodic boundary conditions.
Would you please guide me how I should prepare the input file for QE such
that it doesn't have any periodic boundary condition?
Thanks in advance.

Yours,
Mohaddeseh
