Dear QE users,
Recently, i am doing simulations for Ar from low density to high density,
including VdW corrections with VdW-DF2 scheme. As i understand, the results
with VdW and without VdW should go to the same at high density. The present
results show that for the pressure, they are the same at high density, but for
the energy, there is visible difference also. So, could anybody explain what's
the problem? I think it maybe because that the VdW scheme does not vanish at
high density, is it?
Best wishes,
