M. D. Fredlund (2000) Bimodal Fit 
The M.D. Fredlund dialog contains the equation parameters necessary to mathematically represent the SWCC curve when using the methodology published by M.D. Fredlund (2000) for the Bimodal Fit. A description of the theory can be found in the SVSOILS Theory Manual.
afb: The afb field refers to a fitting parameter in the M.D. Fredlund (2000) Bimodal equation.
nfb: The nfb field refers to another fitting parameter in the M.D. Fredlund (2000) Bimodal equation.
mfb: The mfb field refers to another fitting parameter in the M.D. Fredlund (2000) Bimodal equation.
jfb: The jfb field refers to another fitting parameter in the M.D. Fredlund (2000) Bimodal equation.
kfb: The kfb field refers to another fitting parameter in the M.D. Fredlund (2000) Bimodal equation.
lfb: The lfb field refers to another fitting parameter in the M.D. Fredlund (2000) Bimodal equation.
Split, s: The Split field refers to the fraction attributable to the first portion of the grainsize curve when starting with the coarse fraction.
Fit: The Fit indicates whether the experimental data has been fit with the M.D. Fredlund (2000) Bimodal equation.
Error: The Error field shows the difference between the fitted data and the laboratory values in terms of R2.
