Re: [Wien] error in elastic calculation

2019-11-18 Thread prasad jayasena
 Dear Prof. Blaha

Thank you very much for your reply . I actually have done a mistake (due to my 
lack of understanding) in the job files. My calculation is spin polarized and I 
had both 
x_lapw dstart -p and x_lapw dstart -up -p/ x_lapw dstart -dn -p enabled. I 
changed it and now my calculation is running (not finished yet, but going okay)

Sorry for taking your time.

Prasad

You calculations gave the first error in  a dstart step.

What says  dstart.error

It looks as if you do not have a full initialization in these 
directories. And remember, dstart needs not only *in* files, but also 
case.rsp/up/dn from  x lstart

Re: [Wien] How to do a spin polarized calculation from a non spin spolarized calculation ?

2019-11-18 Thread Laurence Marks
Rather than removing the Broyden files, an alternative is to inject a Pratt
step. To do this, look at the values of the GREED (i.e. grep :MIX case.scf)
and chose a moderately small number, e.g. 0.025. Then do "echo 0.025 >
.pratt". This injects a single step without losing the memory.

For reference, a reason why convergence can be poor is because the steps
that have been taken are either too large or too small for good Simplex
gradients. Injecting a single step along the residue direction is a gentler
approach than removing the history completely.

Re: [Wien] [SPAM?] Should the valence electrons configuration of charge transfer insulators be changed ?

2019-11-18 Thread Peter Blaha
WIEN2k is an "ab initio" method. You cannot assign a certain number of 
VALENCE electrons to a specific atom. Only core electrons are specific 
to an atom and its occupation can be constraint.


The term "charge transfer insulator" describes a situation if the CBM 
and VBM has states on different atoms, thus an excitation changes the 
"valence" of the atoms. In contrast, a Mott insulator would have CBM and 
VBM on the same atoms (eg. a d-d transition and an excitation does not 
change the charge state.
A charge transfer insulator does not require that you move electrons 
around yourself.


However, often such systems are not well described by standard GGA 
calculations and you may need LDA+U, EECE or hybrid-DFT.
This is also not "ab initio", because you have to make the decision and 
use for metallic fcc Co standard GGA, but for CuO GGA+U, but thats at 
the moment the state of the art.

Re: [Wien] How to do a spin polarized calculation from a non spin spolarized calculation ?

2019-11-18 Thread Peter Blaha
I don't know from where you have this recipe, but it does not work. From 
a non-spinpolarized calc. you cannot go to a spin-polarized solution.


For difficult spin-polarized calculations you may need more than the 40 
default iterations. Continue and specify more iterations (-i 80 or more).


Sometimes, if the mixer really gets confused, it might be necessary to 
trick it. If the solutions oscillate, do 1-2 PRATT cycles (rm *.broy*) 
or try MSEC3 instead of MSR1.


Most of the time, a better k-mesh (more points) and/or Temperature 
broadening (TEMP/S with max 0.010) may help. But don't forget at the end 
to reduce the broadening again (0.002 ~ Room temperature)


If you want to "help" mixer to reach convergence in a really difficult 
situation (and come out of a unclear situation) you could use the FSM 
method.  Suppose you do a supercell of 200 Fe atoms (this would probably 
be a "difficult" system), you can estimate the total spin as 200*2.2 and 
do arunfsm -m 440.

Hmmm. If you put the excited state into the system it goes into the LUMO as
you say in 3), in general the wrong place. Therefore I will argue that
treating it as "gone" via a Slater method in EELS makes physical sense. I
don't agree with the physics of adding it back as a real electron, sorry,
as background seems the only appropriate way.

N.B., of course, if due to the core hole (fractional or full) previously
unoccupied states at the target atom drop below the Fermi energy they will
now get filled which can be unphysical. I can't see how one avoids this for
a metal or a small gap insulator within standard DFT; neither the mixer nor
lapw2 currently have atom occupancy constraints. Using runfsm can avoid
this in some cases.

Re: [Wien] error in elastic calculation

2019-11-18 Thread Peter Blaha

We can only "guess".

You calculations gave the first error in   a dstart step.

What says   dstart.error

It looks as if you do not have a full initialization in these 
directories. And remember, dstart needs not only *in* files, but also 
case.rsp/up/dn from   x lstart

Dear wien2k developers and users

I am not sure whether there is another forum or place to send my 
previous question regarding elastic property module comes with wien2k 
module. I really appreciate if someone can reply to my previous post 
regarding the issue in running rhomb.job etc.


Thank you and kindly expecting your support.

Dear users

I need to calculate elastic constants of a cubic material. I tried to 
use the instruction given in the wien2k user guide and could create 
elastic, rhomb, tetra and eos directories successfully ( init_elast and 
elast_setup). But I am unable to run any of the other job scripts 
rhomb.job, tetra.job etc.


My system is spin polarized. So This is how I tried it.

Re: [Wien] How to fit the E(M) results using the FSM procedure ?

2019-11-18 Thread Peter Blaha

Write a shell script, which is very simple:

#!/bin/tcsh -f
foreach i (0.0 0.5 1.0 1.5 2.0 2.5)
   runfsm -m $i 
   save moment_$i
end

Thanks Pr Blaha for your answer and now I have another question

Is there a possibility to do one calculation for many values of M using 
FSM procedure as in case of the volume optimization ?
