Re: [Wien] Potential bug with initso_lapw in version 18.2

2019-07-03 Thread Peter Blaha

After some additional info I can verify the problem.

It happens in cases WITH inversion symmetry, when you run init_so 
several times and the number of equivalent atoms has been changed by a 
previous init_so.


The problem is in the init_so script, which does not update the original 
case.in2 file, because there is a previous mv instead of a cp command.


You can find in init_so_lapw (wien2k_19) or in initso_lapw (version 18)

...
 if(! -e $file.in2c_so &&  -e $file.in2_so && ! -z $file.in2c_so 
&& ! -z $file.in2_so ) mv $file.in2_so $file.in2c
 if(! -e $file.in2c_so &&  -e $file.in2_so && ! -z $file.in2c_so 
&& ! -z $file.in2_so ) mv $file.in2_so $file.in2


In the first line above, the "mv" should be a "cp" (copy instead of 
move), otherwise case.in2 cannot be updated anymore in the next line and 
the next init_so produces a wrong in2c file.


Regards and thanks for the report

Dear Developers,

I was having similar problems to what is described in the mail below:

https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg07758.html

Basically, when I do initso_lapw, and wanted to use the new structure 
for SO calculations, the case.in2c file was causing the lapw2 to crash. 
I did realize that the reason is because the case.in2c file is not 
taking the GMAX value from case.in2 at all. I had to manually enter it 
myself into case.in2c after initso_lapw is done. I want to emphasize it 
again: case.in2c does not have the GMAX at the last row only when you 
accept the new structure for SO calculations.


The question I would have at this point is: Will I need to manually fix 
the case.in2c from this point on, or is there a patch I can use to fix 
this issue once and for all. I also want to add that this particular 
problem does not occur in the older versions.


Best,

Ucar

Hi,

I cannot verify this problem. In my tests I always get a proper and 
complete in2c file.


Can you send me privately your struct file and describe your 
magnetization direction, where the problem occurs.

Yes. You can "miss use" mixer for that.

Make sure there is no case.clmcore nor an clmsum_old file, just a

Re: [Wien] potential

2016-09-02 Thread Peter Blaha

Vcxoul can have pos and neg. values.

Rho should be positive everywhere. However, when you plot the density of 
only one state, rho can get zero easily in large parts of the unit cell 
and thus by numerical inaccuracies even small !!! negative densities may 
pop up, in particular if you are not well converged (RKMAX) or have a 
density with sharp nodes, ...

The resulting case.clmval is used as the input charge density. I know
that the Y00 term in case.clmval is different from Y00 term in

It should be, as rho >= 0. I should not worry if it is *quite*
close to xero.

What's the sign convention used in the output files of critic2? I notice
that there are positive and negative values in both vcoul.cube and
rho.cube. Maybe it is OK to have both positive and negative vcoul.cube. But
what does it mean to have both positive and negative date in rho.cube? Or
is it just numerical inaccuracy?

In WIEN2k the energy zero point is the average of the potential in the
interstitial region. Is it already shifted in case.vcoul?

Re: [Wien] potential

2016-08-31 Thread Peter Blaha

As mentioned before, you should not use case.vsp/vns.

But there is a more or less "standard" method:

Instead use the R2V option in lapw0 and create case.vtotal.

The potential in this format can be used in lapw5 (see UG) to create V 
on a grid in a single plane.


You can also use   prepare_xsf_lapw   (see UG) to create a 3D grid of 
the potential (in a format suitable for viewing in xcrysden, but I'm 
sure it can be converted easily to other formats).

Re: [Wien] potential

2016-08-31 Thread Alberto Otero de la Roza
Hi Yundi,

You can write real-space grids of WIEN2k potentials, densities, or
combinations of them using critic2
(https://github.com/aoterodelaroza/critic2). Use this input:

crystal case.struct
load wien case.vcoul case.struct vnorm id vcoul
load wien case.clmsum case.struct id rho

cube cell 50 50 50 field vcoul file vcoul.cube
cube cell 50 50 50 field rho file rho.cube
cube cell 50 50 50 field "$vcoul*$rho" file vrho.cube

You load the crystal structure with "crystal", then the electrostatic
potential (case.vcoul) and the total density (clmsum). Note the
"vnorm" keyword selects the correct normalization for the
potential. The following cube entries write 3d grids in Gaussian cube
format with 50 points along each axis for the potential (first line),
the density (second), and the product of the two.

Best,

Alberto

I am 99% certain that there is nothing which will do this
automatically for you, some work will be required.

I am pretty certain that you can use the R2V option in case.in0 to
output vtotal. You would then need to do something like use lapw5 to
generate a number of different slices, or use lapw3 (modified input)
to generate the Fourier coefficients than do your own Fourier
transform of them.

N.B., you will have to pay attention to norms and be careful otherwise
it will be GIGO.

Re: [Wien] potential well depth

2015-02-26 Thread Peter Blaha

Now we start to understand what you want.

You have to create manually some distorted structures (corresponding to the
potential well you want to investigate) and calculate E-tot.
Then plot E-tot vs. distortion.

It is your task, to define the distortions (eg. in SrTiO3 it could be a
simple rigid rotation of the octahedra, but that could be done in various ways,
or there could be (additional) tilting, .
