Hi

we have recently used BLYP-D and PBE-D for NPT
calculations of water. In both cases the density
at normal conditions improved considerably,
e.g. for BLYP from 0.8 g/ml to 0.97 g/ml.
Similar improvements were reported for water clusters
and interfaces.
I would say that these methods are currently the
best compromise of accuracy and computational cost
for molecular liquids.

best regards

Juerg
