to improve convergence

Mohamed

Hello,

I'm using VOF unsteady model to modelize a water jet I have a problem with continuity convergence, since it attempts 0.01, it statrs to fluctuate (between 0.009 and 0.03). I've modified the under-relaxation factor and timpe steps to improve this convergence but it was vain... Do you know if 0.01 of continuity convergence value is enough in such case? else is there any way to imrove it?

Thanks in advance, Mohamed
