GetStepToleranceOptions Method (ICWNonLinearStudyOptions)

Gets convergence and equilibrium parameters.

.NET Syntax

Visual Basic (Declaration) 
Sub GetStepToleranceOptions( _
   ByRef NEqilibriumIteration As System.Integer, _
   ByRef NMaxEqilibriumIteration As System.Integer, _
   ByRef DConvTol As System.Double, _
   ByRef DPlasticityTol As System.Double, _
   ByRef NSingularityEleFactor As System.Double _
)
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
 
instance.GetStepToleranceOptions(NEqilibriumIteration, NMaxEqilibriumIteration, DConvTol, DPlasticityTol, NSingularityEleFactor)
C# 
void GetStepToleranceOptions( 
   out System.int NEqilibriumIteration,
   out System.int NMaxEqilibriumIteration,
   out System.double DConvTol,
   out System.double DPlasticityTol,
   out System.double NSingularityEleFactor
)
C++/CLI 
void GetStepToleranceOptions( 
&   [Out] System.int NEqilibriumIteration,
&   [Out] System.int NMaxEqilibriumIteration,
&   [Out] System.double DConvTol,
&   [Out] System.double DPlasticityTol,
&   [Out] System.double NSingularityEleFactor
)

Parameters

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

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.
