FAQ 005304 | How can I create a nodal support with the "Partial Activity" nonlinearity...

Question:
How can I create a nodal support with the "Partial Activity" nonlinearity via the COM interface?

Answer:
The following VBA macro shows the creation of a nodal support with the "Partial Activity" nonlinearity. The source code can be found under Downloads.

Option Explicit

'---------------------------------------------------------------------
Sub SetNSupports()
'---------------------------------------------------------------------
Dim model As RFEM5.model
Dim data As IModelData
Dim support(0) As RFEM5.NodalSupport
Dim ISup As RFEM5.INodalSupport
Dim ISupPA As RFEM5.IPartialActivity
Dim nlPA As PartialActivity

1. Set model = GetObject(, "RFEM5.Model")
2. model.GetApplication.LockLicense

1. On Error GoTo e

1. Set data = model.GetModelData

1. support(0).No = 1
2. support(0).NodeList = "1"
3. support(0).SupportConstantX = -1
4. support(0).SupportNonlinearityX = PartialActivityNLType
5. support(0).SupportConstantY = -1
6. support(0).SupportConstantZ = -1
7. support(0).RestraintConstantX = -1
8. support(0).RestraintConstantY = -1
9. support(0).RestraintConstantZ = -1

1. data.PrepareModification
2. data.SetNodalSupports support
3. data.FinishModification

1. Set ISup = data.GetNodalSupport(1, AtNo)
2. Set ISupPA = ISup.GetNonlinearity(AlongAxisX)

1. nlPA.PositiveZone = CompleteActivityType
2. nlPA.PositiveSlippage = 0.005
3. nlPA.NegativeZone = FailureActivityType

1. data.PrepareModification
2. ISupPA.SetData nlPA
3. data.FinishModification

e: If Err.Number 0 Then MsgBox Err.Description, , Err.Source

1. Set data = Nothing
2. model.GetApplication.UnlockLicense
3. Set model = Nothing

End Sub
