Zero-length angular expansion joint simulation problem
Thread Content
The questioner is learning online *how to create angular expansion joints. However, the angular expansion joints made following the steps in the instructional video always have the following problems. Do any of you have any valuable suggestions? The angular expansion joint issues appear at 30-31; it’s the last one. But I can make it work by entering the length. I really don’t understand it that well.

It’s not necessary to enter the information shown in the first diagram. When you create a connection from 30 to 31, there must be a length specified； The correct approach is: 1. Remove the pipe segment from 30 to 31 ； 2. Open the restraints at the midpoint of either the 31-40 or 20-30 segment, and add constraints for 31 and 30. You can enter NODE30 and CNODE31; use RY as the type, just as you did in the first diagram.
This 0 length is needed to install hinge-type expansion joints; why do several people say it’s not necessary? !
