Hi

You cannot observe anything just from residuals if they are going straight. In case of VoF analysis that's pretty usual. But that doesn't mean that the solution is not converged. Try to use some other monitor, like variation in velocity at some point, like exit etc. If this variation is very small with iterations, that means solution is converged.

yes residuals can be meaningless. Use monitors and flux reports.
