Hi,

I am using Star-ccm+ to simulate Taylor bubbles generated by a cross-shaped junction in 2D. The models I used are:
Eulerian multiphase
Implicit unsteady
Laminar
Segregated flow
VOF

I found that there are always some errors around the bubble I generated which is shown in the picture attached. problem.PNG
I tried to increase mesh number from 10k to 50k but it still doesn't work. Any suggestion to reduce these errors?

Thank you.
