Crate pravash 

Pravash — Fluid dynamics simulation for AGNOS

Sanskrit: प्रवास (pravash) — journey, flow

Particle-based and grid-based fluid simulation. SPH for real-time effects, Euler/Navier-Stokes for accurate simulation, shallow water for surface waves. Built on hisab for math foundations.

Modules

• sph — Smoothed Particle Hydrodynamics (particle-based fluids)
• grid — Euler/Navier-Stokes grid-based solver
• shallow — Shallow water equations (2D surface waves)
• [buoyancy] — Buoyancy and drag forces
• [vortex] — Vortex dynamics and turbulence
• common — Shared types: FluidParticle, FluidConfig, material properties
• error — Error types
