NLSLAYER,<curvefit>,[B],[S],[refStrain],[Vis]

Define a nonlinear soil layer data set for the soil module. User can curve fit and not define any other properties for the curve. Otherwise, the user must define all of the curve properties.

• curvefit - auto fit the curve.
  • 0 = not using curve fit
  • 1 = using curve fit
• B - Beta
• S - S exponent
• refStrain - reference strain
• Vis - viscosity
