I think the code can use both at the same time, but it doesn't seem to me a good idea to add VdW interactions twice: once with non-local functionals, once with semi-empiric corrections Paolo On Fri, Oct 27, 2017 at 10:12 PM, Saif Ullah wrote: > As per my limited

As per my limited knowledge, only one option can be used. vdW-df is non-local, so it does not need C6 etc. On Fri, Oct 27, 2017 at 6:10 PM, Eleftheria Gkogkosi wrote: > Hello, > > Is it acceptable to set input_dft='vdw-DF' and then also use > vdw_corr='DFT-D' in order to

Hello, Is it acceptable to set input_dft='vdw-DF' and then also use vdw_corr='DFT-D' in order to adjust london_c6(1) parameters? Or does one have to choose between a) non local functions (e.g. vdw-DF) and b) london correction to the, say, PBE functionals? -- Eleftheria Gkogkosi Applied

Hi Friends,​I am trying to optimize a supercell using vc-relax. In a first step, I used the space group to optimize one unit cell which gives a reasonable cell volume. Later, when I tried using same unit cell to optimize a supercell using ibrav = 14, unit cell volume keeps on shrinking and

The error you have might be due to insufficient memory, but projwfc.x does not (or should not) require more memory than the corresponding scf calculation. Please provide your scf input (if it doesn't take a week to run) Paolo On Thu, Oct 26, 2017 at 2:14 PM, Martin Gmitra
