Dear vasp users,

I got an error message when I try to calculate the polarization with "LCALCPOL". Can someone tell me what is this error ?

Thank you in advance

I had this same problem. It seems that LCALCPOL is not compatible with setting NPAR. It is probably related to the fact that the polarization is calculated using a different k mesh.

An error occurs during the generation of the k-kpoints set (symmetry breaking division scheme in KPOINTS). Use more symmetric division scheme.
