To create CBUSH elements:

1. Select the elem types panel on the 1D page.

or

Select Element Types from the Mesh pull-down menu.

2. Choose the 1D subpanel.

3. Click spring= and select the CBUSH element type.

4. Click return.

5. Create an orientation vector using the vectors panel.

6. Select the springs panel on the 1D page.

7. Click property= and select the property with the PBUSH card image loaded.

8. Click the orientation vector toggle switch to orient vector.

There are three alternatives for orienting the CBUSH element:

A) You select a vector which was created using the two nodes option:

-      If the first node in the vector definition (from node) is the same as end A of the CBUSH element, the second node of the vector definition (to node) is added as a direction node (G0) in the element definition.

-      If the first node in the vector definition (from node) is not the same as end A of the CBUSH element, a direction vector (X1, X2, X3) is added to the element definition which is the direction of the selected vector resolved into the local coordinate system assigned to end A.

B) You select a vector which was created using the base & magnitude or cross product options:

-      A direction vector (X1, X2, X3) is added to the element definition, which is the direction of the selected vector resolved into the local coordinate system assigned to end A.

C) You want to use a local coordinate system (CID) to define the element coordinate system:

-     Click the orientation vector toggle switch to no vector.

-     Perform steps 9 and 10.

-     Select the card editor icon from the tool bar .

or

Select Card Editor from the Setup pull-down menu.

-     Click the switch and select elems.

-     Select the CBUSH elements that you want to edit.

-      Select config= and select springs.

-      Select type= and select CBUSH.

-      Click edit.

-      To use a local coordinate system as the element coordinate system, click on the CID field (on the far right) and select a local coordinate system from the graphics window.

-      Click return.

9. Click the upper node and select end A from the graphics window.

10. Click the lower node and select end B from the graphics window.

Once you select the second node , HyperMesh creates the CBUSH element.
