DFT-D2 parameters for tungsten

Why do you want to use the D2 parameters? The D3 set of parameters is much 
more reliable and the D2 set should no longer be used. If you want to 
obtain system-specific coefficients, I recommend to read Ehrlich et al. 
(2011) System-Dependent Dispersion Coefficients for the DFT-D3 Treatment of 
Adsorption Processes on Ionic Surfaces. ChemPhysChem 12(17): 3414-3420.
