Hello,

I running an ionic relaxation of 32 carbon atoms in a carbon nanotube,
which ends at the 17th timestep with:

Code: Select all

 17 F= -.28864087E+03 E0= -.28864087E+03  d E =-.101552E-04
 curvature:   0.00 expect dE= 0.577-262 dE for cont linesearch  0.167-262
 ZBRENT: fatal internal in brackting
         system-shutdown; contact gK immediately
This sounds like a serious problem.
I'm using parallel version of vasp.4.6.28.

The essential input and output files are here:

Is my input not right?

Regards,
Rob.

SIGMA = 0.0
May cause some problem - it would be better if you set it to a very small value (e.g. 0.001) ...

I would be interested in seeing your input values from above, but the link doesn't work.Can you repost it maybe?
