Hi Wasut, the wall constant for a wall boundary is not rescaled (check the
description of the physical unit):
The rescaling by width^2 is only needed because a harmonic bias can be
defined on multiple variables, with very different units.
Note, however, than in the latest versions you have the ability to define
walls as a separate bias (and also change its force constant umbrella
sampling-style). The current syntax that you are referring to will remain
for backward compatibility.
