VDW_A1
VDW_A1 = [real]
| Default: VDW_A1 | = 1.0 | for DFT-D3 with the BJ damping function |
Description: VDW_A1 defines the damping function parameter [math]\displaystyle{ a_{1} }[/math].
VDW_A1 sets the damping function parameter [math]\displaystyle{ a_{1} }[/math] for the DFT-D3 (BJ damping function) and DFT-D4 methods.
