Re: [Wien] Inconsistency in kgen

Hi, Yes, my fix was not correct. The bct and bco lattices are special cases and are also discussed in literature. While the direct lattice vectors in bct have all the same length, the reciprocal lattice is face-centered tetragonal and thus they have different length. Nevertheless as far as I

Thank you Prof. Marks, yes the composition is same & also the k-points are same. For 10% uncertainty I would go and complete the calculation for structure 2. On Tue, 19 Mar 2024 at 22:07, Laurence Marks wrote: > Assuming that the composition is the same and the technical parameters are > compara

Assuming that the composition is the same and the technical parameters are comparable, I would say that there is a 90% probability that the one that converged in 25 iterations is lower in energy -- and a 10% uncertainty. --- Professor Laurence Marks (Laurie) www.numis.northwestern.edu https://scho

Dear Wien2k users, I have a basic question regarding convergence achieved in structural model. If we see that one type of structure (with definite space group symmetry) converge smoothly with much less number of iteration ~ 25 iterations while another type of structure with

Dear Prof. Peter Blaha, I think I found another issue with kgen -1 mode especially concerned with I4/mmm symmetry. As previously mentioned, the '-1' mode of kgen generates uneven k divisions, as you rightly pointed out. However, I've observed potential issues with the weight of the uneven k
