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've not looked too closely at the UDF. Have a look for the near wall cell macros: ie tag the cell(s) that touch the wall and assign the source that way. Or split a layer or two of cells out of the main domain using Registers and the Mesh Split functions.Â
