VDW_S6 = [real] 

Description: VDW_S6 sets the global scaling factor or steepness factor in the damping functions of van der Waals methods.


VDW_S6 allows to set the value of a parameter in damping functions:

Mind: VDW_S6 is not used in the implementation of DFT-D3 in VASP, which means that [math]\displaystyle{ s_{6} }[/math] cannot be modified. However, the setting of [math]\displaystyle{ s_{6} }[/math] with VDW_S6 is possible with the simple-DFT-D3 package.
