At which point is such a calculation hanging? When lapw0 is running?
Beside this, I don't think that there is a problem with a calculation if
finally you could converge it.

After force minimization with LDA or PBE, then do the mBJ calculation
without -fc. -fc is necessary if you do geometry optimization, which you
can not do with mBJ.

Subject: [Wien] regarding hanging of job and mBJ

Dear Wien2k users,

A. Sometime my jobs are hanged without completing a scf cycle after couple
of cycle.
So, I do two things: 1. clean_lapw and re-run the scf cycle and 2. without
do a clean_lapw I simply re-run the scf cycle.
In both cases I get conversed scf.

Is there any problem with such a calculation?

B. I know the better way to run mBJ is to either first complete a
convergence with PBE or LDA and then proceed for mBJ.
my question is: If I run PBE/LDA calculation with a force minimization (and
get minimum force withing required limit) then is it also needed to run mBJ
for force minimization or we can run simply for charge and energy
convergence? I can test it but limitations of resources not permit me to do
this test.
