Is there any solution for "LAPACK: Routine ZPOTRF failed 1" when applying esternal electrostatic field in slab. My simulation died after relax one Ionic step. Any suggestion will be highly appreciated. As shown below:
1 F= -.11576990E+05 E0= -.11576981E+05 d E =-.115770E+05
BRION: g(F)= 0.499E+04 g(S)= 0.743E+09
bond charge predicted

Re: There is a puzzling problem in applying esternal field
LAPACK error often appears because of mistakes in input.
E.g. when two atoms have identical coordinates.

So could you give me some good suggestions and solutions for input parameters, such as Mixing-tag ? Thank you.admin wrote:LAPACK error often appears because of mistakes in input.
