    The following code can be used:

        # create contact:
        Connections=ExtAPI.DataModel.Project.Model.Connections
        newContact=Connections.AddContactRegion()
        # modify contact type and define friction coefficient:
        newContact.ContactType=ContactType.Frictional
        newContact.FrictionCoefficient=0.2
        ExtAPI.DataModel.Tree.Refresh() # refresh tree to see modifications
        # select contact and target faces:
        sourceSel=ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities) # create empty selection
        sourceSel.Ids=[137] # define Ids of faces to be included
        newContact.SourceLocation=sourceSel # apply selection to contact side
        targetSel=ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
        targetSel.Ids=[164] # define Ids of faces to be included
        newContact.TargetLocation= targetSel # apply selection to target side

    Note - if the aim is to use Named Selections to define the Contact and Target region

    • There is no need to use script to change the scoping from Geometry selection to Named Selection, Mechanical will automatically change this if a Named Selection is used in a scoping.

    • To grab an existing Named Selection, one way it to use its name. GetObjectsByName returns a list of all the Mechanical objects that have a given name, if that name is unique, using the first object in the list will work:

    my_NS_1 = ExtAPI.DataModel.GetObjectsByName('my_NS_1')[0]
    newContact.SourceLocation = my_NS_1
