Weibull Function 
The Weibull Function dialog contains the equation parameters necessary to mathematically represent the compression curve with the Weibull Function. A description of the theory can found in the SVSOILS Theory Manual.
awb: The awb field refers to one of the fitting parameter for the Weibull Function.
bwb: The bwb field refers to another fitting parameter for the Weibull Function.
ewb: The ewb field refers to another fitting parameter for the Weibull Function.
fwb: The fwb field refers to another fitting parameter in the Weibull Function.
Minimum Stress Limit: The Minimum Stress Limit is used to designate a lowermost value on the void ratio versus total stress relationship. Consequently, the Minimum Stress Limit becomes the lowermost value that can be used for volume change calculations. As the minimum stress limit approaches zero there could be some difficulty in obtaining a converged solution and the solution may not be truly representative of actual conditions.
Fit: The Fit field indicates whether the fit algorithm has been successfully executed on the current data.
Error: The Error is the difference between the fitted results and the laboratory values in terms of R2.
