Yes I did.
But there are a few things I wasn't quite sure.
1. In the example, there are nodes 5-10, 10-15, 25-30. Should I also put node 20-25?
2. Also, I put the distance from node 10 to 15 as the maximum allowed travel distance provided by the manufacturer. But if the piping expanion is larger than this, it still passes the code with a very low stress.
3. What is the difference between K1(stiffness for forces below the yield force FY) and K2(stiffness for forces greater than FY)?
