Missing HIST file for PIMD [SOLVED]

Dear ABINIT Community,

In running test v7#08 with Abinit-7.8.2, files with extensions IMG#_GSR.nc are created but no HIST file is printed. Shouldn't there be a HIST file for restarting with restartxf=-1?

ANADDB Character Table for spgroup 194 [SOLVED]

Hello Abinit Users, This is a general (and probably easy) question and hence no input files are attached. According to the Bilbao website, for spgroup=194, the character table contains 12 elements. For example, for 4f Wyckoff positions, the B1g Raman mode is characterized by: 1 -1 1 -1 1 -1 1 -1 1 -...

Re: Missing PHVEC file for self-consistent phonon calculatio

I noticed that one of the moderators of this forum is also an author of PRL111,025503(2013). I would very much appreciate knowing at least which version of Abinit could be used for self-consistent phonon analysis using SCALID.

Gratefully,

Missing PHVEC file for self-consistent phonon calculation

Dear Abinit Users, I have successfully run tests t85, t86, t87, and t88 of v5. My understanding is that by the end of t88, three files t88.out_PCINFO, t88.out_PHFRQ and t88.out_PHVEC should be generated to be used as input to test t100. I get the first two files but the t88.out_PHVEC is not printed ...

Additional information on freeze_displ

Dear Abinit Users,

In the m_phonon_supercell.F90, the displaced xcart values (from their equilibrium values) are given in the freeze_displ_supercell subroutine whereas the displ function is defined in alignph.F90. Is there a reference used for these definitions?

Thanks,

Re: Crash when ionmov=13, optcell/=0

In case others may run into the same problem, my way out of this crash is to lower dtion to say 0.2 or 0.1. This seems too small but it will not diverge dilatmx.

Re: DC electrical conductivity

Plot the ac conductivity (i.e. sigma(omega)) versus omega and extrapolate the curve to omega=0. That gives you the dc conductivity.
