"Simulate the fluid on any surface with full control"





    Fluid Simulator for Grid-Curve (New v2.1):

        • Fluid Simulation for Grid-Curve- Realistic fluid simulations on rectangular grids or curves as the grid base.
        • Multiple Solver Types- Choose a fluid solver from Fast and Exact options.
        • Custom Profiles- Add custom profiles to control specific areas of the fluid simulation for curve(s) based grid.
        • Multiple Boundary Types- Choose from Open, Wrap, and Solid (Wall) boundary options.
        • Viscosity and Vorticity- Realistic fluid behavior with field-based viscosity and vorticity (turbulence).
        • Dynamic Color and Velocity- Fluid reacts to collider objects (Mesh, Curve) for dynamic color and velocity effects.
        • Seven Forces Nodes- Precise control over fluid motion with seven customizable forces nodes.
        • Field-based Dynamic Settings- Artistic control using field-based settings for the entire simulation. 



        Fluid Simulator for Mesh (New v2.1):

          • Fluid Simulation on Any Mesh- Simulate fluid on any mesh surface, including open, closed, quads, and triangles.
          • Multiple Solver Types- Choose a fluid solver from Fast and Exact options.
          • Easy Mesh Boundary Definition- Define the mesh boundary easily using attributes, providing control and customization.
          • Viscosity and Vorticity- Realistic fluid behavior with field-based viscosity and vorticity (turbulence).
          • Dynamic Color and Velocity- Fluid reacts to collider objects (Mesh, Curve) for dynamic color and velocity effects.
          • Seven Forces Nodes- Precise control over fluid motion with seven customizable forces nodes.
          • Field-based Dynamic Settings- Artistic control using field-based settings for the entire simulation.



          Fluid Particle Advector for Fluid Simulators (New v2.1):

            • Particle Advection- Advect particles based on the fluid simulator, working seamlessly on grids, curve-grids, or meshes.
            • Damping Factor- Fine-tune particle behavior using field-based damping factors, allowing precise control over their movement.
            • Dynamic Color and Velocity- Adjust particle color and velocity dynamically, taking cues from collider objects like Meshes or Curves.
            • Collision- Option to add particles collision with the external geometry as well as with other particles.



            Bake

            The Blender 3.6, 4.0, and 4.1 have the baking feature for the Simulation Nodes of the Geometry Nodes. To bake: Select the Object having the simulation nodes -> Physics Tab -> Simulation Nodes (Bottom) -> Press Bake. It will bake and store the cache next to the project file.

            About

            This is a node setup and is made with simulation nodes of the geometry nodes for Blender 3.6, 4.0, and 4.1. So, basic knowledge of geometry nodes is needed to use this tool.


            License

            You can use this tool in any of your projects (non-commercial or commercial).

            You may not redistribute the geometry node group itself, for free or commercially.


            Happy Noding... :)
