Dear Stefaan, dear all,
I doing calculation for AFM phase of LaMnO3.
I followed suggestion of Stefaan, and accept all changes of symmetry
proposed by nn and sgroup. I did all the initialization without any
problem, the only thing I am not sure I did correctly is the preparing of
afminput. It asks me if the 1/1 , 1/2 ... atoms have the same spin density
Does it mean that the occupation of spin up for atom 1 is equal to the
occupation of spin down for atom 2? If so, I did not understand why it
asked me also for 1/1 ...?
In any case, lapw0 ran succesfully without any errors, while I got
uplapw1.error
Cholesky INFO = 225
'SECLR4' - POTRF (Scalapack/LAPACK) failed.
and in the LMNO3.dayfile is written
start (Tue Oct 14 15:08:38 CEST 2003) with lapw0 (20/20 to go)
>; lapw0 (15:08:38) 61.870u 0.290s 1:04.06 97.0% 0+0k 0+0io

>; stop error
may be it is connected with the fact that I did not understand correctly
how to make input for afm calculation.
Yours, Natalia Perkins
