SPH is a mesh-free particle method for simulating fluids and other materials.
- The state of a system is represented by a set of particles
- The particles possess material properties
- They interact with each other within the range controlled by a smoothing function
- The discretization of the equations of motion is based on the discrete particles
- And the local properties (density, velocity, etc.) are calculated using a variety of particle based formulations
- Pressure is calculated from the density using an equation of state
- Then pressure acceleration
- Other effects (e.g. viscosity) can also be included
