The Connections object provides an API for the Connections tree object.

To access the Connections object:

connections = Model.Connections

The Connections object exposes several convenient methods for adding connections. For example, you can add a beam or set the contact type to frictionless on one of the model's contact regions:

beam = connections.AddBeam()

contact_region = connections.Children[0].Children[0]
contact_region.ContactType = ContactType.Frictionless

Beam objects require a valid scoping. You can satisfy this requirement by setting the appropriate property. For a beam, you set the ReferenceLocation and MobileLocation properties:

reference_scoping = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
reference_scoping.Ids = [110]
beam.ReferenceLocation = reference_scoping
mobile_scoping = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
mobile_scoping.Ids = [38]
beam.MobileLocation = mobile_scoping

For the above beam, accessible properties include:

beam.ReferenceBehavior = LoadBehavior.Deformable
beam.ReferencePinballRegion = Quantity("0.001 [m]")
beam.Radius = Quantity("0.005 [m]")
beam.MobileZCoordinate = Quantity("6.5E-03 [m]")
beam.MobilePinballRegion = Quantity("0.001 [m]")
