We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

This is my mesh quality:

Minimum Orthogonal Quality = 7.48746e-02 

Maximum Aspect Ratio = 3.21902e+02 

In VOF, I selected implicit and in phase interaction surface tension coefficient is constant 0.072N/m, surface tension force modelling is enabled.Viscous as SST K omega.

In solution methods, scheme is PISO and also tried with coupled and simple. and first or second-order upwind both and pressure as PRESTO! all other settings were kept deafault.
