HI @no240805, I've copy/pasted your scene and it runs perfectly on my installation. Do you have any displayed error on the terminal when launching the scene ?

I try it in ubuntu23.10 ,but it doesn't work as yours.
I download and run the SOFA_v23.06.00_Linux.run .

Ok, I cannot give support on non LTS version of Ubuntu... If the problem is related to your Ubuntu version then I simply cannot try it myself.
But before jumping into this conclusion I would need more information : can you give me the output prompted when you launch the simulation ? It should look a bit like that :
