If a component has the Shared Topology property set to
Shared (or Merged in Ansys 15.0 and 16.0), then that component and
all components beneath it become a share group.
The Shared Topology property of components lower in the structure are
ignored, so you can't use them to create sharing exceptions.
For example, if you set Shared Topology to true for the root component,
then the entire model will be one share group.
The name of the component node is the name of the component from which
recursive sharing starts.
The bodies under this node are listed with full path names through the
assembly, such as Axle Sub-Assy (Front)\Wheel (Left)\Solid, using component
names in parentheses if they are present.
You can have multiple distinct share groups, but a body can only belong to
one group.
