OFIELD KAPPA

OFIELD_KAPPA = [real] 

Description: The tag OFIELD_KAPPA sets the strength of the bias potential in the Interface pinning method.

---

The bias potential in the Interface pinning method is written as

[math]\displaystyle{ U_\text{bias}(\mathbf{R}) = \frac\kappa2 \left(Q_6(\mathbf{R}) - A\right)^2 }[/math].

The tag OFIELD_KAPPA method sets the strength of the bias potential [math]\displaystyle{ \kappa }[/math]. The unit of [math]\displaystyle{ \kappa }[/math] is [math]\displaystyle{ \textrm{eV}/(\textrm{unit} \,\, \textrm{ of }\,\, Q)^2 }[/math].
