Hi everyone,

I have a problem simulating a rising air bubble in liquid water in a closed cavity 2D.
I tryed different models (VOF, Euler,..) but everytime I get the same problem:

As soon as I include the surface tension the bubble seems to explode..(see in picture)

Bubble Radius is very small 0.4 mm and surface tension is 0.073 n/m

Does anyone know this problem? What could be the reason?

Any help would be appreciated.

Best, Lucas
