FE Joints Panel
Use the FE joints panel to create, review, or update joint elements. A joint element is a definition of a connection between two rigid bodies. Joint elements store a property and orientation information.

Create Subpanel
Option | Action |
---|---|
joint type | Choose the joint type to create. |
orientation | Select the orientation
type. Only appears in the PAM-CRASH 2Gsolver interface. |
nodes | Select the appropriate number of nodes for the selected element. |
Update Subpanel
- Changing Types
- Changing a spherical joint that uses orientation nodes to any other joint type causes the orientation value to be set to none and the nodes eliminated from the element, except in the case detailed below.
- Changing Nodes
- When an element's nodes are being updated, only the nodes specified are replaced. The other are left unchanged. For example, changing a 6-noded joint's nodes and picking nodes 2 and 6 leaves nodes 1, 3, 4, and 5 the same. Nodes 2 and 6 are then updated.
- Changing Properties
- Properties are updated for all selected elements if the box is checked.
- Changing Orientation
- Changing the orientation of non-spherical joints to nodes causes the update operation to fail for that joint. The failed joint is then placed in the saved mark.

reject | Reject the recent changes made. |
review | After each joint element is selected, its type, orientation and property is displayed in the panel. |
update | An update menu is displayed. Select the desired items to update type, nodes, property, orientation. Only the selected information is updated. Joints that cannot be updated are placed on the saved mark. If you click elements and then select retrieve on the extended entity selection menu, the failed entities are highlighted. |
