====== NLSOIL Command ======

NLSOIL,<Opt>,<NSTimeSunInc>,<DispConv>,<ForceConv>,<EqualIt>,<BedInt>,<NLDampType>,<MMmult>,<SMmult>

This command sets the global nonlinear [[SASSI:SOIL]] options for the soil module. This command does not change any information for the linear soil model.

  * Opt - flag to use nonlinear soil
    * 0 - do not use nonlinear
    * 1 - use nonlinear
  * NSTimeSunInc - Sub-increments per timestep 
  * DispConv - Displacement convergence error
  * ForceConv - Force convergence error
  * EqualIt - Equilibrium iterations
  * BedInt - Bedrock interface
    * 0 - Rigid
    * 1 - Viscoelastic (Currently Disabled)
  * NLDampType - Damping Type
  * MMmult - Mass Matrix Multiplier
  * SMmult - Stiff Matrix Multiplier
