Treat as Remote Mass
In studies where you are not interested in the detailed results of a
solid body, you can consider its effect on the rest of the structure by
treating it as a Remote Mass.
The remote mass functionality is available for Static, Frequency, Linear
dynamic, and Buckling studies. This functionality is not available for
large displacement solution in Static
studies.
To treat a body as a remote mass:
In the Simulation study tree, right-click a solid
body in an assembly component or multi-body part, and select Treat
as Remote Mass.
In the PropertyManager,
for Faces, edges, or vertices for Remote
Mass 
, select the faces, edges, and vertices that
connect the body to the rest of the model. These entities can only deform
as a rigid body.
The selected entities should
represent the actual interface with other bodies. Using additional surface
areas, edges, or vertices results in over-stiffening the structure. You
may need to use the Split
tab, or Split Line tool to define
faces that represent the actual contact areas.
Select Apply
Force/Moment at CG to apply forces and moments at
the CG (Center of Gravity) of the selected body.
Click 
.
Note:
You cannot connect a remote mass to a body that was previously treated
as a remote mass.
