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.

Please check the mesh aspect ratio, and change in cell size around the inlets. I suspect the cells are OK for single phase, but you need a fine mesh with very low aspect ratio and growth rate for most multiphase applications. 

If the population balance allows bubbles to grow in regions of low shear, how does that plot tie up with the bubble size? How is the bulk flow behaving?Â
