How can I create a contact region through scripting?

Pernelle Marone-Hitz

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
