You can create a retained nodal degrees of freedom (DOFs) boundary condition to specify the degrees of freedom that are to be retained as external to a substructure. This boundary condition can be created only in a Substructure generation step.
To create or edit a retained nodal DOFs boundary condition:
Display the retained nodal DOFs boundary condition editor using one of the following methods:
To create a new retained nodal DOFs boundary condition, follow the procedure outlined in “Creating boundary conditions,” Section 16.8.2 (Category: Mechanical; Types for Selected Step: Retained nodal dofs).
To edit an existing retained nodal DOFs boundary condition using menus or managers, see “Editing step-dependent objects,” Section 3.4.13. To edit the region to which the boundary condition is applied, see “Editing the region to which a prescribed condition is applied,” Section 16.8.4.
Toggle on any of the following options:
| U1 | Nodal freedom in the 1-direction. |
| U2 | Nodal freedom in the 2-direction. |
| U3 | Nodal freedom in the 3-direction. |
| UR1 | Rotation about the 1-axis. |
| UR2 | Rotation about the 2-axis. |
| UR3 | Rotation about the 3-axis. |
