RBE3 Panel
Use the RBE3 panel to create, review, and update RBE3 elements.
Location: 1D page
RBE3's are interpolation constraint elements, where the motion of a dependent node is defined as the weighted average of the motions of a group of independent nodes. The dependent degrees of freedom and weighting factors can be specified or automatically calculated based on the geometry. RBE3 elements are element config 56 and are displayed as lines between the dependent node and the independent node(s) with RBE3 displayed at the dependent node of the element.

Option | Action |
---|---|
dependent |
|
independent nodes | Select the desired independent nodes from your model. |
dependent dofs: (checkboxes) | Select the degrees of freedom to transfer from the dependent node to the independent nodes. |
weight = | Specify the decimal
proportion (0-1) of the force and moment loads distributed from
the independent nodes to the dependent node for the selected
DOF's. Note: The proportion of moment load
distributed will also be affected by the geometry (distance)
between the dependent and independent nodes.

elem types = | Select an element type. |

Input | Action |
---|---|
elem | Select the desired RBE3 element. |
connectivity | Determines which
additional fields display in the third column of the panel.
|
dofs | Determines which
additional fields display in the third column of the panel.
Note: When you update the DOFs, only legal DOF
values are accepted.
|
weight factors | Determines which
additional fields display in the third column of the panel.
|
elem types | Select a element type
to change the RBE3 to. This option determines which additional fields display in the third column of the panel. In this case, only the elem types= field displays. Valid element types depend on the current solver profile. |
Command Buttons
Button | Action |
---|---|
create | Create the new RBE3 to your specifications. |
update | Change the selected RBE3 to use the currently defined characteristics. Once updated, you can no longer reset to the original values. You can only reset to the updated values. |
reject | Undo the most recent create action. |
review | Click review, then select a RBE3 element. The selected RBE3's characteristics display in the subpanel's entry fields. |
reset | Reset the entry fields to their starting values (the RBE3 element's currently assigned values, as opposed to any changes you might have made without clicking update.) |
