[Pw_forum] Applying vdW to only part of a system

[Ian Shuttleworth]

Is it possible to apply vdW forces to only a part of system?

I am thinking of examples where, for example, a vdW adlayer (e.g. benzene)
sits on a surface, and surface doesn't need vdW corrections.

If I add the vdw_corr toggle (or if I set an appropriate value
to 'input_dft') I've understood that vdW are applied to the entire system -
if this is right, how could I make this option more selective?

With thanks

Ian
