Dear all:
Could u tell me how to fix the object in the center of the window all the time in paraview?
Because after multiple time steps, the bubble always runs out of the paraview window, I have been searching for a long time but I can't find out how to do it, currently I am manually clicking on each frame individually.

The details are as follows: this is what the bubble looks like when it remains in the center at the initial moment.


After a certain time step the bubble will run out of the paraview‘s window
