Dear all, I am trying to understand the effect of van der Waals interactions in the stability of various systems. For example, I simply took helium dimer and did "scf" calculation, in one case, using the full "rVV10" functional and another calculation omitting the nonlocal part (VV10),i.e. using "sla+pw+rw86+pbc" as "input_dft", keeping all other parameters unaltered. The results indicate that the nonlocal VV10 part destabilizes the system. Is it consistent? What is the explanation behind it? And is there any provision in the code so that the nonlocal contribution can be printed in the output file? * QE version: 5.1.2 *
