antiferromagnetic relaxation

#1 Post by razaullahshahbacha » Thu Jan 25, 2024 12:07 pm

Greetings,
I am doing relaxation calculations for the antiferromagnetic system with the MAGMOM tag. Although the calculation has started but i am getting the following message in the std.out.

You use a magnetic or noncollinear calculation, but did not specify |
| the initial magnetic moment with the MAGMOM tag. Note that a |
| default of 1 will be used for all atoms. This ferromagnetic setup |
| may break the symmetry of the crystal, in particular it may rule |
| out finding an antiferromagnetic solution. Thence, we recommend |
| setting the initial magnetic moment manually or verifying carefully |
| that this magnetic setup is desired.

The INCAR is provided below;
ALGO = Normal
EDIFF = 1.0e-8
EDIFFG = -0.05
ENCUT = 700
IBRION = 2
ICHARG = 0
ISIF = 3
ISMEAR = 0
ISPIN = 1
ISTART = 1
KPOINT_BSE = -1 0 0 0
LAECHG = True
LCHARG = True
LEPSILON = True
LORBIT = 11
LSORBIT = .TRUE.
SAXIS = 0 0 1
LREAL = Auto
LVHAR = True
LWAVE = False
LNONCOLLINEAR = .TRUE.
MAGMOM = 3*64*0.0 3*96*0.0 3*96*2.0 3*96*-2.0
NELM = 100
PREC = Accurate
SIGMA = 0.05


Thank you

Dear razaullahshahbacha,

Could you please provide all relevant input and output files for your calculation according to the forum guidelines.

| For optimal performance we recommend to set |
| NCORE = 2 up to number-of-cores-per-socket |
| NCORE specifies how many cores store one orbital (NPAR=cpu/NCORE). |
| This setting can greatly improve the performance of VASP for DFT. |
| The default, NCORE=1 might be grossly inefficient on modern |
| multi-core architectures or massively parallel machines. Do your |
| own testing! More info at https://www.vasp.at/wiki/index.php/NCORE |
| Unfortunately you need to use the default for GW and RPA |
| calculations (for HF NCORE is supported but not extensively tested |
| yet). |
