<div>Dear Garrett,</div><div>If I understand your question correctly, this affects all range-separated hybrid functionals, i.e. all functionals with an explicit short/long-range Coulomb or Gaussian potential contribution. This warning is relevant if you as a user have to choose some parameters of the functional on your own. If all parameters of the functionals (CUTOFF_RADIUS, OMEGA) are pre-defined by the functional like in HSE06, you may ignore this warning. In the case of HSE06 with omega=0.11, you will probably not be able to get rid of this warning in real-case scenarios because with usual values of EPS_DEFAULT of at most 1.0E-10, this cutoff radius is at least at the order of 20 A.</div><div>HTH,</div><div>Frederick<br /></div><br /><div class="gmail_quote"><div dir="auto" class="gmail_attr">xuan wang schrieb am Freitag, 3.
