I am trying to account for Vander waals correction in VASP. Now doing this for PBE is easy all one has to do is set IVDW=11
but the VASP webpage for DFT-D3 says that
Mind: The default values for the damping function parameters are available for the following functionals: PBE (GGA=PE), RPBE (GGA=RP), revPBE (GGA=RE) and PBEsol (GGA=PS). If another functional is used, the user has to define these parameters via the corresponding tags in the INCAR file.
Furthermore they also specify that, among all of the parameters in the damping function, $s_{R,6}$ and $s_8$ are the ones whose values depend upon the functional. But I can not find what value to choose when I am doing electronic calculations with HSE06. Considering that HSE06 is a combination of PBE and Exact coorelation, perhaps the value for PBE(default one) should work fine. But I am not sure!!
