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.

I'm not suggesting changing anything: your model seems to be doing exactly what you've told it. 

If the fluid domain expands due to information from the Mechanical solver that extra volume needs to be filled with fluid. That fluid must enter the new larger volume from somewhere. If there isn't enough flow from the inlet where else can it come from?Â
