[Pw_forum] vdw-df2

[florence liu]

Dear all,
i have been looking through the file Modules/funct.f90 and i have found
something which confuses me a little.
according to the file the vdw-df2 functional is "defined" as
"sla+pw+rpb+vdw2". however the corresponding reference (Lee et al., Phys.
Rev. B 82, 081101 (2010)) mentions that the the revPBE exchange is replaced
by the PW86 exchange. Doesn't that mean that the vdw-df2 should rather be
"nox+pw+rw86+vdw2" ? or am i totally wrong?

best wishes,

florence
