The pairwise dispersion energy must sum up to the total dispersion energy, if it does not I would consider this a bug. This behavior is enforced in s-dftd3 and dftd4:
Thanks. Yes, the list output of pairwise in classic dftd3 was misinterpreted in the harness when forming the full array. Fixed in MolSSI/QCEngine#385 at https://github.com/MolSSI/QCEngine/pull/385/files#diff-c2513a32098e0b14751980a1524320abc60b8cc1a883aacd76399e69949ebb0a
Seems to be resolved now.
This is purely informative and for searchability; feel free to close right away.
I noticed in debugging sapt0-d3m in Psi4 that the pairwise analysis from classic
dftd3 -anal
and simple-dftd3 (at least the qcengine interface) differ by a factor of two. Below are the rms of the returned arrays (labels are<program>_<conda channel>
), but I've checked the arrays per-element, too. s-dftd3 is closer to dftd4, so I'm assuming that it's classic dftd3 that's the inconsistent definition. Rather than perpetrating another variation in d3 versions out there, I'll compensate in Psi4.
