Springs Panel

Use the Springs panel to create spring elements.

Location: 1D page

A spring element is an element created in a space between two nodes of a model where a spring connection is desired. In Radioss, three noded or four noded springs can be created.

Spring elements store a property and a degree of freedom (DOF).

Spring elements are element config 21 and are displayed as a line between two nodes with the letter K written at the centroid of the element.

Springs can translate to CELAS2 in Nastran or *SPRING in Abaqus.

Create Subpanel

Note: The Create subpanel is not available in the Radioss solver interface.
Option Action
node 1
Select the first end of the spring element.


Figure 1.
node 2
Select end b of the spring element.
Note: Once you select both end a and end b, Engineering Solutions creates the spring element.

no vector / orient vector
orient vector
Select an orientation vector.
no vector
Do not assign a vector.
dof1 - dof6 Select the degree of freedom (DOF) that applies to the element.
property Select a property to which the entity should point.

Spring2, Spring3, Spring4 Subpanel

Use the Spring2, Spring3, and Spring4 subpanels to create two noded, three noded, and four noded springs.
Note: Only available in the Radioss solver interface.
Option Action
node Select the nodes to create spring elements between.

In the Spring3 subpanel, use the third node selector to select the direction node.
orientation Choose a method for orienting springs in 3D space.
node
Select a node to specify the vector orientation.
vector
Use the standard plane and vector selector to determine the orientation of the spring.
components
To be used if the direction of the local y axis of the spring is to be specified by entering the X, Y, and Z components.

Command Buttons

Option Action
reject Revert the most recent change.
review After each spring is selected, Engineering Solutions indicates which degree of freedom (dof1 through dof6) is active for the element, and also displays the appropriate values after property = .

This function assumes the spring element is active and on the screen.

To make a spring element with the same degree of freedom as an existing one, review the existing element. This places the appropriate degree of freedom and property into the panel.
update Implement the changes made in the panel.
return Exit the panel.
