How can I create groups of groups for the geometry in Mechanical ?

Below is a code sample to illustrate how this can be done.

First, create a list of bodies that you would like to group:

bodies = ExtAPI.DataModel.Project.Model.Geometry.GetChildren(DataModelObjectCategory.Body,True)
folder1 = ExtAPI.DataModel.Tree.Group(bodies)
folder1.Name = "My folder"

Then, to place this group inside another group, the trick is to grab the folder itself and group it:

folder2 = ExtAPI.DataModel.Tree.Group([folder1])
folder2.Name = "My top folder"

Finally, the tree has to be refreshed for the display to update:

ExtAPI.DataModel.Tree.Refresh()

Result is as follows:

To add, say we have 2 springs and want to add them to a folder:

spt=[]
spt.append(ExtAPI.DataModel.GetObjectsByName("Longitudinal - Ground To Sup")[0])
spt.append(ExtAPI.DataModel.GetObjectsByName("Torsional (Beta) - Ground To Sup")[0])
folder1 = ExtAPI.DataModel.Tree.Group(spt)
folder1.Name = "My_springs"
