​the forces are in <>.scf, so you can look at the end of that file or


grepline :for <>.scf 10


where <>.scf => real name of scf

10 => # of lines you want to see. "grepline" lists the last '#' lines of the "<>.scf​" file that have ':for' or :FOR', so you will see the results of the last iteration, but posibly of earlier iterations as well.

the numbers you will see are not '0' but small ~ 1-5, 5 is fair, 1 is good.

step 1: read the usersguide (search for the keywords 'relax' or 'optim')

step 2: study Peter's wien2k workshop slides at 
http://www.wien2k.at/reg_user/textbooks/WIEN2k_lecture-notes_2013/ , in 
particular

http://www.wien2k.at/reg_user/textbooks/WIEN2k_lecture-notes_2013/WIEN2k-getting_started.pdf 
: this one contains information about a.o. relaxation

http://www.wien2k.at/reg_user/textbooks/WIEN2k_lecture-notes_2013/Exercises_13.pdf 
: this one contains exercises about a.o. relaxation

After having done this, most likely your question will have been solved.

Stefaan
