SetStepToleranceOptions Method (ICWNonLinearStudyOptions)

Sets convergence and equilibrium parameters.

.NET Syntax

Visual Basic (Declaration) 
Function SetStepToleranceOptions( _
   ByVal NEqilibriumIteration As System.Integer, _
   ByVal NMaxEqilibriumIteration As System.Integer, _
   ByVal DConvTol As System.Double, _
   ByVal DPlasticityTol As System.Double, _
   ByVal NSingularityEleFactor As System.Double _
) As System.Integer
Visual Basic (Usage) 
Dim instance As ICWNonLinearStudyOptions
Dim NEqilibriumIteration As System.Integer
Dim NMaxEqilibriumIteration As System.Integer
Dim DConvTol As System.Double
Dim DPlasticityTol As System.Double
Dim NSingularityEleFactor As System.Double
Dim value As System.Integer
value = instance.SetStepToleranceOptions(NEqilibriumIteration, NMaxEqilibriumIteration, DConvTol, DPlasticityTol, NSingularityEleFactor)
System.int SetStepToleranceOptions( 
   System.int NEqilibriumIteration,
   System.int NMaxEqilibriumIteration,
   System.double DConvTol,
   System.double DPlasticityTol,
   System.double NSingularityEleFactor
System.int SetStepToleranceOptions( 
&   System.int NEqilibriumIteration,
&   System.int NMaxEqilibriumIteration,
&   System.double DConvTol,
&   System.double DPlasticityTol,
&   System.double NSingularityEleFactor


Frequency of performing equilibrium in number of solution steps
Maximum number of equilibrium iterations for any solution step
Relative displacement tolerance used for equilibrium convergence
Tolerance for strain increment for models with creep or plasticity

Stiffness singularity elimination factor:

  • normal solution if set to 1
  • if <1.0, then the program modifies stiffness terms causing singularity to help convergence

If normal solution fails, trying a different value; for example, 0 may help convergence.

Return Value

Status as defined in swsNonLinearStudyOptionsError_e
