I can only guess. It will help if you put your case.in0,1,2 and struct & klist somewhere I can reach them. I am hardly going to steal them! N.B., you should relax the base 15x1x1 positions first. --- Professor Laurence Marks (Laurie) www.numis.northwestern.edu https://scholar.google.com/citations

Dear Professor Laurence Marks, * I returned the mixing parameter value back to 0.2, thanks a lot for the comprehensive explanation in "Mixing for Dummies"; * I set the new values of the spheres using setrmt –a Ba:2.10,Ti:1.78,O:1.61 ; * Then I copied the case.struct_setrmt file to case.structure

Did you follow my suggestion and not use -it? It appears that you did not. I would not use it until :DIS is less than 0.05, and perhaps not even then. You are still being incomplete about the information you provide: On Tue, Apr 2, 2024 at 1:34 AM Natalia Andreeva wrote: > Dear Professor Laurenc

Dear Professor Laurence Marks, Thank you very much for your reply. I will try to reveal the question of what I use for the calculation. * The error occurs immediately when the first calculation cycle has not yet completed. * No, I don't use runsp, the vacuum value is 25au and RMT=5.20 * I have a s

 I am trying to calculate a sufficiently large 2x3x15 supercell  based on a tetragonal barium titanate (BaTiO3) cell. In this calculation, I create an oxygen vacancy and a surface. The calculation is successfully Sufficiently large ??? I'd say, it is MUCH too large. 2x3 ?? either use 2x

You have not provided enough information for a full diagnosis. When does this occur, right at the beginning? Are you using runsp? How much vacuum? What RKMAX? Do you have ELPA? What version of Wien2k? K-points? Minimisation? Which iterative? When are you using the iterative, in the 2nd cycle? Some

Dear Win2k users, I am trying to calculate a sufficiently large 2x3x15 supercell based on a tetragonal barium titanate (BaTiO3) cell. In this calculation, I create an oxygen vacancy and a surface. The calculation is successfully initialized with the parameters of atomic spheres equal to Rmt(Ba)=
