HILLS_BIN

HILLS_BIN = [Integer]
Default: HILLS_BIN = NSW 

Description: HILLS_BIN sets the number of steps after which the bias potential is updated in a metadynamics run (in case VASP was compiled with -Dtbdyn).

---

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

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

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

The number of steps after which the bias potential is updated is set by HILLS_BIN.
