Hello,
   If in regular scf force is less than 5, no need to run mini. If it is not, then run. From case_struct_lastmini, you will get optimized positions. See change in diff in position bet starting and last one may it it after 3rd or 4th place of decimal.
best wishes.

Dear wien2k master:
    I wanna use mini_lapw to optimize the internal position of atom in unit cell, my questions are as follows:
    (1)run regular scf first , and rerun mini_lapw -p -I -j "runsp_lapw -I -fc 1.0 -cc 0.001 -ec 0.0001 -i 200", but the :FGL*** and :FOR***
==================
:FGL002:   2.ATOM               -11.083898500   -11.083898500     0.000000000 partial forces
:FGL002:   2.ATOM               -11.066220831   -11.066220831     0.000000000 partial forces
:FGL002:   2.ATOM               -11.139406381   -11.139406381     0.000000000 partial forces

:FGL002:   2.ATOM                 1.842720223     1.842720223     0.000000000 total forces
-------------------------
:FOR002:   2.ATOM         16.284          0.000          0.000        -16.284 partial forces
:FOR002:   2.ATOM         16.131          0.000          0.000        -16.131 partial forces
:FOR002:   2.ATOM         15.675          0.000          0.000        -15.675 partial forces
:FOR002:   2.ATOM         15.650          0.000          0.000        -15.650 partial forces
:FOR002:   2.ATOM         15.753          0.000          0.000        -15.753 partial forces
:FOR002:   2.ATOM         15.820          0.000          0.000        -15.820 partial forces
:FOR002:   2.ATOM         15.809          0.000          0.000        -15.809 partial forces
:FOR002:   2.ATOM          2.606          0.000          0.000          2.606 total forces
=============================
it seems that just one step the force meet the criterium, but i set -fc 1.0 , how can it stop since the force still bigger than 1.
      (2)After the mini process, and assume it meet the criterium, where can I get the new struct ? ( I check the .struct, it is not updated)
      Thanks:)
 
Hui
