1) I am using version 13.1. Still, min_lapw has changed the space group number from 14 to 4, which I only noticed after Gerhard had pointed this out. The regular scf cycle was done with the correct space group in .struct and produced "X-FORCE for atom 1 is not zero as required by symmetry". The

Dear Gavin, you are probably right about the wien2k preferences. Originally, the struct file has this: 14_P21/n, which is changed to 4_P21/n during minimization. I did not have any problems with these settings when just running a single scf (no structural optimization). Thanks, Kateryna > Wien

Wien2k is probably not designed to use P21/n but uses P21/c. Struct file before change from 14 to 4 is for P21/n, P21/c, or both? On Apr 23, 2014 11:35 AM, wrote: > Dear Laurence, Peter and Gerhard, > > thanks for your comments. Some answers: > > 1) I am using version 13.1. Still, min_lapw has ch

but still the line P6 4_P21/n is wrong either 14_P21/n (sgroup -> 14 P21/c) or 4_P21, these two things are not the same ! Ciao Gerhard DEEP THOUGHT in D. Adams; Hitchhikers Guide to the Galaxy: "I think the problem, to be quite honest with you, is that you have never

Possible reasons: bug in some older version and/or a mistake made in one of the input files caused by a "handbook not read error". Note: only the Bi atoms (atoms 2 and 3, but not 1, 4, 5, 6) are in positions without free parameters where the forces have to be zero by symmetry. Seems that in yo
