Modifying the boundary condition applied to the pin
Objects that you can create and modify in certain steps—such as boundary conditions, loads, and interactions—have special managers that allow you to modify objects and change their status in different analysis steps.
Context:
In this section you will use the boundary condition manager to modify the boundary condition NoSlip so that translation in the 1-direction and rotation about the 2-axis are unconstrained during the loading step.
Currently the Boundary Condition Manager displays the names of the two boundary conditions that you have created as well as their status in each step: both boundary conditions are Created in the initial step and Propagated through the following analysis steps.
In the Boundary Condition Manager, click the cell labeled Propagated that lies in the row labeled NoSlip and in the column labeled Load, as shown in Figure 1. That cell becomes highlighted.
Figure 1. Select boundary conditions to edit in the Boundary Condition Manager.
On the right side of the manager, click Edit to indicate that you want to edit the NoSlip boundary condition in the Load step.
The Edit Boundary Condition dialog box appears, and Abaqus/CAE displays a set of arrows on the model indicating where the boundary condition is applied and which degrees of freedom are constrained.
In the editor, toggle off the buttons labeled U1 and UR2 so that the pin is allowed to translate in the 1-direction and rotate about the 2-axis. Click OK to close the dialog box.
In the Boundary Condition Manager, the status of the NoSlip boundary condition in the Load step changes to Modified.
