differentiate between thickness, b, (dimensional aperture) and (hydraulic) aperture, a, (cubic law).
In faults, permeability is now computed as k_init + da^2 / 12.
Then, the diffusivity term is scaled by b0.
Changes in a originate from dilation/lift-off: da.
Then, a = d0 + da. We also set b = b0 + da, i.e. da=db.
