@Shen-Zhen-Xiong I'm trying to testing your system with the newest LibRI. but your system is much large and complex, it is common to have hard convergence.
For reference. issue #3343 contain some calculation example of myself.
@Shen-Zhen-Xiong I've changed your input setting by:

And use the separate_loop method to do HSE calculation.
the SCF performance is good at the beginning, but after some EXX step and inner loop, the SCF convergence is also bad, with the first electronic step out of EXX loop always have the 1.5e-05 DRHO and the SCF process is stuck there. Luckily it will finally converge

@PeizeLin @WHUweiqingzhou Do you have any comment ? I consider the convergence performance have some improvement space.
Thanks you very much, when changing to exx_separate_loop 1 and mixing_beta 0.2 is ok, but there are some performance improvement.
