Thank you Sir. I got it! I should put 4.98 for LiAB2. On Mon, 11 Mar 2024 at 19:21, Peter Blaha wrote: > Putting RKmax=5 is almost right. Actually you should even put it > accurately to 2 digits after the comma. > > Am 11.03.2024 um 14:15 schrieb shamik chakrabarti: > > Dear Wien2k users, >

Putting RKmax=5 is almost right. Actually you should even put it accurately to 2 digits after the comma. Am 11.03.2024 um 14:15 schrieb shamik chakrabarti: Dear Wien2k users,     I am trying to calculate lithiation voltage of AB2 compound. For that I have two opti

Dear Wien2k users, I am trying to calculate lithiation voltage of AB2 compound. For that I have two optimized structures of AB2 & LiAB2. Now, the minimum Rmt at AB2 is 1.8 & hence if I put Rmt*Kmax=7, it would give Kmax 3.89. Again, the minimum Rmt of Li in LiAB2 is 1.2

Hi, Thank you very much for your report. I can confirm the problem. Both, for bct and bco lattices (body-centered tetragonal or orthorhombic) kgen enforced in default modes equal divisions of the reciprocal lattice vectors (as it should be for bcc). This was not a good choice and the selectio

A structure optimization of a magnetic structure with several TM atoms may take many iterations. You should probably start out with a normal runsp -fc 2 -orb -p -i 80 (it may not converge in 40 cycles ?). Then inspect the forces. How large are they ? If they are larger than 5 mRy/bohr, it
