Hi, I am doing a simple simulation of a slug bubble rising through a cylindrical pipe.
The initial state looks like this:

I did a transient simulation expecting the bubble to rise upwards, however in my simulation, the bubble breaks down as shown below:

What should I do to ensure that the bubble doesn't break to this extent. There should be some amount of wake - I expect that but this is too much.
