Hi, Team
I'm writing code for automation in Ansys Mechanical and I need to select only the outer faces, but I am not sure how to approach it.
I would appreciate if you could give me some ideas or point me to some code that allows me to make a named selection of the outer faces.

See this example. It uses code from the Bolt Tools Add On to make this easier. This code is also in the project file as a suppressed python code object in the tree. There are two examples: fully enclosed block and a block that is open on one end.
#import from the bolt tools add on import sys BoltToolsDir = ExtAPI.ExtensionManager.GetExtensionByName("BoltTools").InstallDir if not BoltToolsDir in sys.path: sys.path.append(BoltToolsDir) import GeoConnectivityHelper GeoConnectivityHelper.Initialize(ExtAPI, Ansys) #Use the bolt tools add on module to get the face connectivity from a starting face StartFacesNs = ExtAPI.DataModel.GetObjectsByName("StartFaces")[0] StopFacesNs = ExtAPI.DataModel.GetObjectsByName("StopFaces")[0] ConnectivityMap = GeoConnectivityHelper.FaceConnectivityMap() ConnectivityMap.BoundaryDefinition="Explicit" ConnectivityMap.StartFaces=StartFacesNs.Entities ConnectivityMap.StopFaces=StopFacesNs.Entities Zones = ConnectivityMap.GetZones() i=1 for Zone in Zones: #Create a new NS to represent the output NewNs = Model.AddNamedSelection() SelInfo = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities) SelInfo.Entities = Zone.Faces NewNs.Location = SelInfo NewNs.Name = "Zone Faces: "+str(i) i+=1
