<Smooth Bridge v2.1 modifier>
I don't think it would work well for fluid meshes that have gaps - it's designed more for topologically consistent meshes, especially those whose gaps are planar or at least have some implied continuity. Have you tried that modifier on arbitrary holes in fluid meshes? I'd be surprised if it achieved a meaningful result...
I've looked into similar algorithms for hole filling in the past, it might be interesting to add to tyFlow at some point, but right now it would be a pretty low priority.
This approach allows ocean fluid simulations to utilize containers of diverse shapes—not just a single box—enabling flexible modular assembly. The regions can then be seamlessly combined into a unified ocean mesh using procedural tools.
Right, that's a planar setup - I thought you were referring to a blobmesh-type setup, like a spray of splash particles or something.
