What terminates the cycle for hybrid HSE run?

[hess8]

Hi, In HSE hybrid functional calculations, the change in the DMP energy is much less than EDIFF, but the loop keeps going.

What determines when the loop stops?

For example I see output for a run with EDIFF at default (10^-4):

Code: Select all
