    I assume this is ANSYS Mechanical…

    Ids = [F.Id for F in MyBody.Faces]

    Hi

    The below example might be what is needed. It assumes one wants 3D solid bodies and then to get their Faces and Ids - if surface bodies are also of interest, then just add to the if: an or condition to get also surface bodies :

    model = ExtAPI.DataModel.Project.Model
analysis=model.Analyses[0]
ns=model.NamedSelections.Children # named selections
for n in ns: # loop through ns 
    nId=n.Location.Ids # only bodies in ns so nId is body id also
    for body in nId: # loop through and find 3D body
        b=ExtAPI.DataModel.GeoData.GeoEntityById(body)
        if str(b.BodyType)=="GeoBodySolid": # if Solid Body (no face/sheets) # or str(b.BodyType)=="GeoBodySheet": # if Solid Body and Surface bodies are used
            faces = b.Faces
            for face in faces:
                fid=face.Id
                print(fid)

    Thank you
    Erik

    Hi Erik
    I am getting this error "iteration over non-sequence of type NamedSelection " because of below code I am not able to get the Id of particular nameselection containing bodies.Please Kindly help me with this.

    model = ExtAPI.DataModel.Project.Model
    ns=model.NamedSelections.Children[3] # named selections
    face1ID = []
    for n in ns: # loop through ns
    nId=n.Location.Ids # only bodies in ns so nId is body id also
    for body in nId: # loop through and find 3D body
    b=ExtAPI.DataModel.GeoData.GeoEntityById(body)
    if str(b.BodyType)=="GeoBodySolid": # if Solid Body (no face/sheets) # or str(b.BodyType)=="GeoBodySheet": # if Solid Body and Surface bodies are used
    faces = b.Faces
    for face in faces:
    fid=face.Id
    face1ID.append(fid)

    print("nameslection ID",face1ID)
