In the post named "HSE06 band structure", the head admin said "Note: A Hartee-Fock calculation can NOT be continued from an existing CHGCAR file, since the non-local exchange is not determined by the charge density but by the density matrix and/or the KS-orbitals." and panda find the evidence for ICHARG=0 at somewhere else. but in another post named "need help with HSE and GW band gap calculations", panda calculated the band structure of Si with HSE using ICHARG=11, and obstained reasonable band gap for Si.

So I am confused on the setting of ICHARG. I also calculated the band structure with ICARG=0 and 11,respectively and got the same band structure.

my question is how to set ICHARG for band structure calculation with HSE functional?
thank you in advance.
