FluidMesh

Bring Your Meshes to Life with Realistic Physics

FluidMesh is a high-performance, surface-physics solution for Unity 6, designed to apply realistic aerodynamic and hydrodynamic forces directly to your 3D models. Unlike standard linear drag, FluidMesh calculates forces based on the actual geometry of your mesh, surface orientation, and fluid density.

Whether you are building a flight simulator, a racing game, or realistic projectiles, FluidMesh enables complex behaviors like Natural Torque and Lift Generation without complex manual tuning.

🚀 Key Features

• Projected Pressure Model: High-fidelity aerodynamics that interact with mesh surface normals for authentic physical responses.
• Lift & Torque: Spin a sphere to see the Magnus Effect, or angle a wing to generate lift—all derived naturally from the shape.
• Performance First: Fully optimized with Unity Burst & the C# Job System. Simulate hundreds of objects simultaneously with minimal CPU overhead.
• Zero-Configuration Setup: Context-aware auto-discovery finds your Rigidbody and MeshFilters automatically. Just drag, drop, and play.
• Wind Integration: Native support for Unity WindZone components, allowing objects to react to environmental air currents.
• Fluid Volumes: Trigger-based overrides for water, high-altitude air, or custom fluid densities.

🛠 Technical Specs

• Unity Version: Unity 6 (6000.0+) recommended.
• Render Pipeline: Agnostic (Works with Built-in, URP, and HDRP).
• Included: Runtime simulation core, custom Inspector tools, CFD-style visualization system, and a comprehensive Demo Scene.
