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

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.
