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.
