Not able to compute PDOS with SOC.

#1 Post by mukesh_jakhar » Mon Jul 17, 2023 3:52 pm

Hello Developers,
I am trying to compute PDOS with SOC. I follow two steps:
First:-
scf calculation
Then copy CHGCAR to DOS folder
DOS calculation.

The same files are working well without SOC tag (LSORBIT = .TRUE.)

When i try to plot PDOS with vaspkit tool. It show only lines(spreaded).
I am attaching my input files for both steps. Can you please help in this regard.

Thanks

Dear mukesh_jakhar,

Your SCF calculation is performed on system without SOC, while in the INCAR file for the PDOS you are you set LSORBIT to true. Have you tried running both calculations with SOC activated using vasp_ncl?

Kind regards,
Pedro Melo

Dear mukesh_jakhar,

I ran you system using a smaller k-mesh and obtained the attached DOS figure.

I do not see any strange issues with it. Could you upload the figure you obtained?

Kind regards,

Dear Pedro Melo,

I'm curious about how you obtained this plot. I performed calculations with SOC and obtained the vasprun.xml file. However, upon attempting to open it using p4vasp, I encountered an error stating "ERROR: Error reading property E_FERMI." Could you offer any insights into this issue? (P.S.: p4vasp functioned correctly before)

Regards,
Hongyang
