Thanks a lot for your comment, Ilya. It was precisely my point that it is "typical for the variable-cell optimization". But it is great to have confirmation that the final structure can be reused without any problems. Best,     Leonid On 10/15/2017 04:41 PM, Ilya Ryabinkin wrote: > Hi

Hi Leonid: you error is typical for the variable-cell optimization: the problem is in the size of PW basis for the fixed energy cutoff. If the size of a cell is changing, there are more/fewer basis plane waves (G vectors)for the same energy cutoff. Just ignore this error and re-run SCF

[Pw_forum] problem with final scf calculation with vc-relax

Dear developers, There are frequent problems with the "final scf" after the convergence of a vc-relaxation with the recalculated G-vectors. In this case, the volume grows during the vc-relax by 3.5%, and G-vectors are assigned from sticks:   dense  smooth PW G-vecs:    dense smooth
