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.

If the liquid fraction is too low to show why is the VOF model a good choice? 

You currently have two distinct fluid domains, and that can make convergence tricky. If you remove the water domain, but set a boundary condition on the water surfaces to reflect the cooling you simplify the model and reduce the cell count.Â
