Procedural Fluid Simulators is a simulation framework powered by Geometry Nodes that allows users to compute fluid dynamics on grids, curve-driven grids, and arbitrary mesh surfaces. It supports both open and closed meshes with various quad or triangle topologies. The system utilizes a field-based workflow, allowing users to dynamically drive simulation parameters like density, temperature, color, pressure, and velocity.

The setup includes multiple solver types, offering both fast processing and high-accuracy modes. It features advanced advection algorithms natively built in, including Semi-Lagrangian, MacCormack, and BFECC methods. Users can apply domain viscosity, vorticity, and collisions with external animated objects. The toolset also bundles advection nodes to drive particles and curves directly from the computed fluid motion variables.
