Hello all,
I am trying to run an scf calculation for calculating charge density for my
system (~450 carbon atoms, a massive graphene sheet). But the calculation
always stops at the same point 'CG style diagonalization..' or 'starting
wfcs are randomized' if I used david style diagonalization.I
The two U terms applied to the two crystallographically distinct Mn atoms
(opposite spin arrangement). Still, I'm expecting to get similar values for
both as they are in chemically identical environments, similar to the NiO
reference.
Thanks,
Hooman

looks like you are applying U twice for Mn atom. what's the difference
between Mn1 and Mn2 site?. different symmetry?. you may have to think
about it.

Dear all,
The following must be an easy fix. I just started to use hp.x for LiMnO2
(hypothetical structure), which is a magnetic (AFM) insulator. I followed
the example02 of the HP code (NiO U parameter) and it worked as expected. I
do the same sequence for the above structure (i.e., magnetic
Another note, there seem to be problems using FFTW interface of MKL
export MKL_DEBUG_CPU_TYPE=5
with AMD cpus. To get around this problem, one hast to additionally set
export MKL_CBWR=AUTO
Kind regards,

Dear Julien,
A slab can never be cubic. At most it can be forced to remain
tetragonal. But I see that your perovskite contains formamidinium
cations. Even if you force the dimensions of the bulk cell to remain
cubic, the internal symmetry after relaxation will not be cubic; those

Dear experts and developers,
I am calculating the phonon DOS of several large cells (30~90 atoms per
unit cell). I found the calculation took too much time and if there is
anything wrong, I need to wait at least I got some results. Could you
give me some advice on how to speed up the

Have you tried to do a SCF calculation for a snapshot with small charges?
If you do not get the same (or at least, very similar) numbers, there is
