Do you know how to solve this "leakage"? Maybe I'm doing something wrong. I'm currently using what appears to be non watertight geometry. For practical reasons, I cannot spend a lot of time trying to fix this geometry. This is only a problem when using the scaled STLs as refinement regions with ⁨`mode inside`⁩. It doesn't always happen, but when it does, it's just a waste of cells when I'm trying to be more economical. It doesn't happen at all if I use the geometry as surface refinement. If there is no simple solution, I'll find some other way which doesn't depend on scaled STLs. https://cdn.discordapp.com/attachments/397874745464586242/1468718139809206314/image.png?ex=698509db&is=6983b85b&hm=12bac6dfa9915c244671f3e355e4b5b6c9480c9a8fe5a72091169c13963eb3d7&
