[Pw_forum] combining vdW-DF and hybrids?

[CONESA CEGARRA, JOSE CARLOS]

hi, 

I am doing some tests with the cvs version of Q-E. I wonder, could one combine the HSE06 functional (that refers only to exchange) with the vdw-DF correlation? I tried a line such as
input_dft='nox+pw+hse+vdw'

but got a message of incompatibility of functionals. 

Also, some question to the developers: 

a) is there work for allowing soon the use of hybrid functionals with USPP or PAW potentials? 

b) will the vdW-DF2 functional be available (with both ions and cell relaxation, if possible) in the 4.3 version? 

All the best,
