Dear developers:
As shown in the question, I performed constant potential simulation calculations in Vaspsol++using the README method. However, when I added the following parameters to INCAR, there was no significant change in the calculation results, except for the effect of solvation. I adjusted the value of EFERMIref, but it did not affect the final result. I want to know where the problem is?
This is my INCAR file:
SYSTEM = relax
ISTART = 0
NPAR = 4
LREAL = Auto
ISPIN = 2
PREC = Accurate
LSOL = .TRUE.
ISOL = 2
capacitance_init = 2
C_MOLAR = 1.0 # set to the electrolyte concentration in mol/L
R_ION = 4.0 # set to the ionic radius in Angstrom
EFERMI_ref = -4.07 # set to the electron chemical potential in eV
