Caesar2 simulates turbine equipment, why are the two ends of the circle drawn fixed?

I don't know if the expansion of the equipment will be reflected if the settings are fixed. During the simulation, a Cnote association node was used between the nozzle and the pipe. Is it because the fixed bracket using this command will change as the equipment expands? Please discuss it and make progress together.
After changing it to continuous, they were connected together. Later, I found a solution. Just define the coordinates. A new problem arose. There is a fixed frame between the two nozzles. Why can it still move with the steel parts? Isn’t ANC fixed?
Will the steel parts also expand and the fixed ends at both ends also move?
The nozzle should be stationary. The expansion of rigid parts is very small.
This simulation is meaningless if it doesn't move. What is important is the effect of the expansion displacement of the rigid part on the nozzle connecting the pipe. This simulates a turbine.
It looks like ANC, but it actually moves with its cnode points. No problem.
If there is no cnonte, it won’t move.
Setting the ANC node through CNODE at the nozzle is just to see the stress on the nozzle, but it is not actually fixed.
