| Define a nonlinear soil layer data set for the [[SASSI:SOIL]] module. The user can curve fit and not define any other properties for the curve. Otherwise, the user must define all of the curve properties. The default value for all of the arguments in this command is 0. | Define a nonlinear soil layer data set for the [[SASSI:SOIL]] module.
