Reference Data
11.0 (2019)

Define the single-directional restraint and guide as usual. Enter a unique node number in the CNode boxes for the single-directional restraint and the guide. Use the same node number for both. Specify the predefined displacements for the CNode.

Guided piping at node 70 rests on a structural member node 1070. The structure undergoes a predefined displacement.

In the example above, ignoring other loads that may be acting on the pipe, the 0.250-inch gap will be closed in the negative X-direction, and the pipe will have a displacement of 0.50-inches in the positive X-direction.
