HILLS H

HILLS_H = [Real]
Default: HILLS_H = $10^{-3}$ 

Description: HILLS_H specifies the height of the Gaussian hill (in eV) used in metadynamics (in case VASP was compiled with -Dtbdyn).

In metadynamics (MDALGO=11 | 21), the bias potential is given as

${\tilde {V}}(t,\xi )=h\sum _{i=1}^{\lfloor t/t_{G}\rfloor }\exp {\left\{-{\frac {|\xi ^{(t)}-\xi ^{(i\cdot t_{G})}|^{2}}{2w^{2}}}\right\}}.$

Thre parameters (HILLS_H, HILLS_W, and HILLS_BIN) must be provided by the user.

The height of the Gaussian hills $h$ (in eV) is set by HILLS_H.
