I withdraw my question. It works with nosym=true.

Subject: pwscf: energy convergence of noncollinear with spin-orbit calculations
To: PWSCF Forum <pw_forum at pwscf.org>
Dear qe users,
I'm trying to calculate total energy of artificial FCC PtFe compound
with magnetic moment (MM) along z- and x-directionsi (MAE).
In order to supress oscillation of moment direction I used for MM||z calculation
input instructions
constrained_magnetization = 'total direction' ,
fixed_magnetization(1) = 0.0,
fixed_magnetization(2) = 0.0,
fixed_magnetization(3) = 1.0,
However I can not reach total energy convergence and it looks like I
still have direction oscillation of MM.
What can be done to resolve this problem?
Thank you in advance.
The complete input file for MM||z is and energy accuracy output file
are attached.
