@duousername1 There is a warning message at the very beginning: WARNING: Total thread number(256) is larger than hardware availability(64). The results may be INCORRECT. Please set the environment variable OMP_NUM_THREADS to a proper value. Please make sure your setup is correct.

@duousername1 Maybe what you expect is OMP_NUM_THREADS=8 mpirun -n 8 abacus

@QuantumMisaka do you have some suggestions on her input?

Larger radius-cutoff (6au -> 8au) of Ce maybe improve the convergence.
mixing_beta
is large and smearing_sigma
is large, you can try other settings.

mixing_beta

is large, you can try other settings. Thank you for your response. I would like to confirm that
1、You mean that replacing the atomic orbital file Ce_gga_150Ry_6au_6s3p3d3f2g.orb with the corresponding atomic orbital file with an 8 cutoff radius will be beneficial for convergence. 2、Additionally, should the values of mixing_beta and smearing_sigma be slightly reduced?
mixing_type: pulay mixing_beta: 0.400000 smearing_method: gaussian smearing_sigma: 0.020000
I look forward to hearing from you.

@duousername1 I'm pretty confident that your setup of multithreading would lead to unconvergence. Would you correct them first, and test if there are further problems?

okay。thanks!I will test it immediately.

With the settings OMP_NUM_THREADS=8 mpirun -n 8 abacus, it still did not converge. The compressed file contains the output。 fp-2.log.zip
Could you please take another look for me? thanks @caic99

"By the way, could you provide me with a Ce atomic orbital with a cutoff radius of 8 au?" thanks
With the settings OMP_NUM_THREADS=8 mpirun -n 8 abacus, it still did not converge.
🤔 Seems this does not help... Sorry for that

thank you very much!
fp-4.log.zip Despite several parameter adjustments, the system still has not converged. The parameters from the most recent adjustment that did not converge are as follows:
INPUT_PARAMETERS calculation relax ntype 6 nbands 400
ecutwfc 150 scf_thr 1e-7 scf_nmax 120

Please take another look at this. I would greatly appreciate @dyzheng
I tried the atomic orbitals corresponding to 8au and 10au yesterday and also modified the input files. INPUT_PARAMETERS calculation relax ntype 6 nbands 400
ecutwfc 150 scf_thr 1e-7 scf_nmax 120

relax_nmax 100 force_thr_ev 0.02 stress_thr 0.5
Unfortunately, it still did not converge. I would like to ask again if there are any other solutions. @dyzheng @kirk0830 @caic99 Once again, I express my sincerest gratitude.
@duousername1 @dyzheng
I tried this example for changing mixing_type, smearing_method and nspin, the convergence still cannot be reached.
Also, by using nspin 2
, the magmom will oscillate
Is nspin 1
correct for this calculation job ?

Thank you for your response. Based on the current situation, it is indeed necessary to consider the issue of spin polarization. You have been a great help. I will proceed to try calculating this system with spin=2. Thank you.

Can you send me your input file and output file for me to take a look at? Thank you @QuantumMisaka

Even the magnetic moments cannot reach to a stationary point, but the magnetic moments seems to be existed.
Describe the bug
When running ABACUS with the following input parameters, the program encountered an error during the SCF calculation. The error messages are:
"!! CONVERGENCE HAS NOT BEEN ACHIEVED !!" "2024-07-25 17:19:53,475 - INFO: job: b131ef03975b49cc0e0af19b716b0ebefcb0fbc3 13911562:job_group_id:12998244 terminated; fail_count is 1; resubmitting job" "2024-07-25 17:19:53,828 - INFO: job: b131ef03975b49cc0e0af19b716b0ebefcb0fbc3 re-submit after terminated; new job_id is 13947468:job_group_id:12998244" The input files are in the following compressed package. init_2.47CeAl2_NH4ClO4_c64_m512.zip
Expected behavior
ABACUS should complete the SCF calculation with errors.谢谢!!
