Yes, I tried. But interestingly, the error repeated :

As others tried to point out, the issue is with wrong placement of “/“. Try
this:
&control
calculation = 'scf’
/
&system
ibrav = 1
celldm(1) = 1.0
nat = 1
ntyp = 1
ecutwfc = 20.0
/
&electrons
/

ATOMIC_POSITIONS crystal
H 0.0 0.0 0.0
K_POINTS automatic

Cheers,

Hello,
Thank you for your response! I apologize for not providing enough details
earlier. I’m attaching the full input file (`test_minimal.in`) that is causing
the error. The latest error message I’m receiving is:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Error in routine card_atomic_species (2):
two occurrences
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
stopping ...
STOP 1
I’ve checked, and there seems to be only one ATOMIC_SPECIES section in my file,
but the error persists. Below is the complete content of my input file:
&control calculation = 'scf' /
&system ibrav = 1 celldm(1) = 1.0 nat = 1 ntyp = 1 ecutwfc = 20.0 /
&electrons /
ATOMIC_SPECIES H 1.00 H.pbe-rrkjus_psl.1.0.0.UPF /
ATOMIC_POSITIONS crystal H 0.0 0.0 0.0 /
K_POINTS automatic 1 1 1 0 0 0 /
I’m using Quantum ESPRESSO version 7.4.1, and the pseudopotential file
(`H.pbe-rrkjus_psl.1.0.0.UPF`) is located in the same directory. I’ve been
manually editing the file and haven’t used copy-paste, but the error keeps
occurring. Could you please help me identify what might be causing this "two
occurrences" issue? Any guidance would be greatly appreciated!
Thank you,
Maliheh Nazari

Please provide the exact input that is causing the error if we want us to fix,
the snippets you are pasting do not provide enough information.
kind regards

A backslash (/) must be ONLY at the end of a namelist.
