yes ,We got total forces at the end of scf files. in all four
NO !!!
You got partial forces, because the scf cycle stopped after the default
of 40 cycles and -fc 0.1 was not converged and thus it never switched
from partial to total forces (check your dayfile !)
PHONOPY is very clever and it checks if the users did not miss that his
calculation is not converged.
continue in the directory 2 with another run_lapw -fc 0.1 and make sure
that it stops because of convergence and not because of 40 cycles.

Yes or no ?

Dear Sir,
We are using the wurzite (structure) of ZnS.
I know that phonopy want primitive cell so i choose the P cell only.
Yes, we have mailed the infromation which the phonopy print

that is

It is assumed that there is no symmetrically-equivalent atoms in

Drift force of 1.scf
0.00053796 -0.00033949 -0.08833666
This drift force was subtracted from forces.
2.scf does not contain necessary information.
Plese check if there are "FGL" lines with

In addition, i also checked the scf file fo each struct file
which is
looking good as per knowledge. in the last of the scf file gives
the sum
of forces.
thank you

Nobody can guess what happened, without more details.
PS: Is this cubic (zinkblende) or wurzite (hexagonal) ZnS ???
Remember Phonopy wants P cells only (no F), and in addition
in some
cases we had problems with hexagonal cases (but others as
yours,
namely to few displacements and thus wrong phonons....)

Dear sir
I want to calculate the phonon spectrum of ZnS using
the phonopy
1.10.0. so in this order, i followed these steps:
mkstruct
init_lapw
phonopy --wien2k -c ZnS.struct -d --dim="2 2 2"
so it generate the four files
ZnS.structS-001
ZnS.structS-002
ZnS.structS-003
ZnS.structS-004
after this process, i calculated the scf file of each
struct file by
making directory of each struct file separetly then
copy into
the ZnS
directory then i would like to compute the total force
so i gave the
command " phonopy --wien2k -f 1.scf 2.scf 3.scf 4.scf "
which showing the following error
[ambeshst@IITJ_HPC ZnS]$ phonopy --wien2k -f 1.scf
2.scf 3.scf 4.scf
