I belive dft-d2 use Grimme D2 parametrization, not D3 parametrization. So the 
results will be similar but not identical.

DFT-D3 corrections

Thanks Ivan for the clarification.
Does setting the dftd3_threebody=.false. implies that it would produce the same 
results as dft-d2?

With regards,
Prasenjit

Dear Sayandeep, Prasenjit
the Grimme D3 correction IS implemented in QE (pw.x, d3hess.x, ph.x). Only the 
three body term of D3 in ph.x is not implemented. For this reason phonon 
calculations should be run with dftd3_threebody=.false.

I was able to run the d3hess program with the input provided in the emails in 
this thread without any problems.

The only (minor) issue I could notice is that the ATOMIC_SPECIES card was 
empty, and it should be filled with the pseudo specification.

Best,
IC
