3DSinghVFX is running the Navier-Stokes equation in Geometry Nodes to achieve a fluid simulation. that's pretty wild!
Hi. In this video tutorial, I have shown how to do procedural fluid simulation on a mesh surface using geometry nodes in Blender 3.6x. I have also shown the presets that do fluid simulation on grid/curve/mesh with full artist controls! The tutorial files and Fluid Simulator presets' download link is in the video description.
Happy Noding ... :)
