After creating a Bolt Pretension with:

newBoltPretension = Model.Analyses[0].AddBoltPretension()

I am wondering how to change the scoping to a Named Selection and how to assign a value. Thank you

    Assuming the NS is ‘Bolt 1‘, with the following it can be assigned to the selection:

    Pretension = Model.Analyses[0].AddBoltPretension()

    BoltObj = DataModel.GetObjectsByName(selection)[0]

    Pretension.Location = Obj

    Assuming that the force to be applied is 1000 N, it can be applied with:

    Pretension.SetDefineBy(1,BoltLoadDefineBy.Load)

    Pretension.Preload.Output.SetDiscreteValue(0,Quantity("1000[N]"))

    The solution was taken from KM #2056373

    # Get Beam objects
myObj = 'Connections'
myBeamsIDs = []
myLoads = [1,2,3,4]

model = ExtAPI.DataModel.Project.Model
obj = ExtAPI.DataModel.GetObjectsByName(myObj)[0]
for beam in obj.Children:
    if 'Beam' in beam.GetType().ToString():
        myBeamsIDs.append(beam.ObjectId)


# Create Bolt Pretension for each Beam
ctr = 0
for beam in myBeamsIDs:
    boltPreTens = model.Analyses[0].AddBoltPretension()
    boltPreTens.InternalObject.GeometryDefineBy = 19  # secret sauce
    boltPreTens.InternalObject.BeamConnectionSelection = beam
    load = Quantity(myLoads[ctr],'N')
    #boltPreTens.Formulation = FormulationType.SmallRotation
    boltPreTens.Preload.Output.Field.Output.SetDiscreteValue(1,load)
    ctr +=1
