• Staggered MAC Grid
• Different advection schemes
  • Semi Lagrangian advection with
    • Bilinear interpolation
    • Runge Kutta and Euler solver
  • PIC advection with bilinear interpolation
  • FLIP advection with bilinear interpolation
  • PIC / FLIP combination
• Pressure solve using the conjugate gradient method with the linear algebra library "Eigen"
• Enforce Dirichlet boundary condition
• Marker particles for air/fluid separation
• Velocity extension using brute force search through grid

Examples:

Youtube video of real time simulation:

• Adaptive time steps
• Vorticity confinement
• Make sure marker particles are outside of obstacles
• Other interpolation alternatives (quadratic, cubic, Catmull Rom)
• Other air/fluid separation techniques (for example level set)
• 3D simulation
