[Wien] how to know stress in Unit cell in Wien2k output

2017-09-23 Thread Dr. K. C. Bhamu
Dear Prof Peter and List, Is there any way to find stress on the Unit cell after/before relaxation? I read the UG but nothing is mentioned about stress there. Regards Bhamu ___ Wien mailing list Wien@zeus.theochem.tuwien.ac.at

This is of course a typo. I'll correct it in the next release. Am 23.09.2017 um 17:30 schrieb karima Physique: Dear Prof P. Blaha and Wien2k users; The unit of the spin susceptibility in the userguide is indicated in (10^6 cm^3 / mol*cell) but when I calculate it I find a value of the order

I guess it is not mentioned in the UG yet (I'll add this ...): Unfortunately, HDLOs can only be used in a regular scf cycle without SO A DOS (with case.qtl from lapw2) should be ok, but x qtl or optic cannot be used with HDLOs). Am 23.09.2017 um 18:39 schrieb Dürrschnabel, Michael: Dear Mr.

Dear Mr. Tran, dear Wien2k users, thanks for the hint. I tested it and it worked fine for the case that you neglect spin-orbit coupling. However, in this particular material system spin-orbit coupling plays an important role and should be switched on in your calculation. If you do so and run

Dear Prof P. Blaha and Wien2k users; The unit of the spin susceptibility in the userguide is indicated in (10^6 cm^3 / mol*cell) but when I calculate it I find a value of the order of 10-6 which seems to me that the unit is (cm^3 / mol*cell) and not (10^6 cm^3 / mol*cell). I just want to know

My opinion is that your first struct file with a = b = 30 bohr = 15.87531 ang and c = 40 bohr = 21.16708 ang was better expect for the bond length as Gerhard mentioned. I would probably put the O atoms around the center in-between z = 0 and z = 1.  In other words, the first atom at: z = 0.5

It should work, however, you must select "VAL", as the R2V files are normalized in the same way as the clmval files, while the clmsum ("TOT") files have a different normalization. Am 23.09.2017 um 11:42 schrieb Ding Peng: Dear Wien2k users, I am runnning wien2k version 16.0 on my Linux PC

My approach. You chose some valid set of experimental knowns, e.g. atomization energies of clusters, heats of formation, reactions using relevant atoms. You then vary the fraction to find the best fit. The value will only be "best" to about 0.05. An alternative that in a few cases worked
