[Wien] structural optimization

[hazem salem]

Dear Wien users,
                          I'm doing structural optimization or a surface using the command:
   
  min_lapw   -j "runsp_lapw -I  -i 100 -fc 1.0", for the topmost two layers, however my calculations stop with forces larger than 1 , about 15 or sometimes more , so what could be the reason of stopping before convergence is obtained?
   
  thank you
  Hazem
