KERNEL_TRUNCATION/FACTOR = real 

Default: KERNEL_TRUNCATION/FACTOR = $\sqrt{3}$ if KERNEL_TRUNCATION/IDIMENSIONALITY = 0
= 1 if KERNEL_TRUNCATION/IDIMENSIONALITY = 2

Description: Determines the spatial extent of the truncated Coulomb interaction relative to the computational cell dimension along the truncation direction.


KERNEL_TRUNCATION/FACTOR defines the cutoff distance of the Coulomb-kernel-truncation boundary. It is expressed as a fraction of the simulation-cell length along the truncated axis (e.g., the surface normal for 2D systems KERNEL_TRUNCATION/ISURFACE).
