[Wien] [Wien2k Users] Input for Hexagonal and Orthorhombic Cells

What do you think is the meaning of:
For option 1-4: specify structure changes in % (each value in separate line)
BIG INPUTBOX
For option 5: specify number of structures: 6, 9 (3x3), 16 (4x4), 25 (5x5), 36

and what are the input boxes in the next line good for?

For option 6: specify number of structures: 10, 27 (3x3x3), 64 (4x4x4), 125 (5x5x5)   INPUTBOX1  specify the % change:   INPUTBOX2

same question for Option 7.

Did you ever check what the script is doing and what is written into the job file ?

Ciao
Gerhard

Betreff: Re: [Wien] [Wien2k Users] Input for Hexagonal and Orthorhombic Cells

For Option 5: a 2D hexagonal structure optimization, we have to vary
both A and C (fully relaxed case) Do we have enter the percentage
change in A and C one below the other or beside each other That is to
say, Do we enter -10
-5
0
5
10
-10
-5
0
5
10
The first 5 represents A and the last five C
Or , we enter
-10 -10
-5 -5
 0 0
5 5
10 10

I do not know how Wien2k takes both of them (how flexible it is) nor has
this been discussed before in the mailing list.
Even for Option 7: Monoclinic case, my same doubt remains where we change
A,B C and gamma I have checked the mailing list and this question has never
been posted before.

Any Suggestions please

Hi Gerhard,

I have exactly the same experience than you but with my grand-mother,
who was using shallot in spite of garlic.
Usually, I am using balsamic vinegar and olive oil ... Just excellent.

OK ! It is certainly not a proper way to use the wien-list (although in
week-end time) so I stop this culinary exchange.

Have a nice week-end

Xavier
