Dear,
I try to use Wien2k + hybrid calculation on a very simple compound MgO
(obviously, this is a test).
The version of wien2k is : WIEN2k_13.1 (Release 17/6/2013).
i) The DFT calculation seems ok.
My batch is
/#!/bin/bash//
// init_lapw -vxc 13 -ecut -6.0 -numk 1000 -b//
// run_lapw -ec 0.0001 -NI //
//exit/
The calculation gives a "GAP" of 4.764 eV (as in exercice 13 of
http://www.wien2k.at/reg_user/textbooks/WIEN2k_lecture-notes_2013/Exercises_13.pdf)
ii) After a /save_lapw/, i use the programs /init_hf_lapw/ (with
NBAND=12 and a 4x4x4 k-point mesh without reduction)
and run_lapw -hf /-ec 0.0001 -NI //and ...
The message are :
LAPW0 END
LAPW0 END
LAPW1 END
mv: ne peut évaluer `MgO.vector': Aucun fichier ou répertoire de ce type
LAPW1 END
mv: ne peut évaluer `MgO.vectorhf_old': Aucun fichier ou répertoire de
ce type
FOURIR2 - Error
> stop error
/
iii) In the log file, I can read :/
(x) lapw0 -grr
(x) lapw0
(x) lapw1
(x) lapw1
(x) lapw2
/In the scratch disk, I find the file called MgO.vector (generated by
the first /lapw1/). But, i don't
have the MgO.vectorhf file (generated by the second lapw1, yes ? no ?)...
I think it is a very "simple" mistake, but i can not find it ... --))
Thanks for your help
Sebastien Petit
