3D SPH Fluid Explosion

Watch fluid dynamics unfold in real-time using Smoothed Particle Hydrodynamics. Adaptive NNC applies k=-1 near shock fronts for improved stability while using k=0 in smooth regions.

SPH Method

Lagrangian fluid simulation using kernel interpolation

Adaptive k

k=-1 at shocks, k=0 in smooth flow regions

50K Particles

Real-time at 30 FPS with spatial hashing

Smoothed Particle Hydrodynamics

SPH represents fluid as particles that carry physical quantities (density, velocity, pressure). Fluid properties are interpolated using kernel functions (Poly6 for density, Spiky gradient for pressure forces).

Try Different Scenarios

  • Dam Break: Classic validation case for SPH
  • Explosion: Outward blast with shockwave
  • Water Drop: Crown splash formation
  • Fountain: Continuous upward jet
