Bases: Base

The liquid material class for SPH.

Parameters:

  • rho (float, optional) – The rest density (kg/m³). Default is 1000.0.

  • stiffness (float, optional) – State stiffness (N/m²). Controls how pressure increases with compression. Default is 50000.0.

  • exponent (float, optional) – State exponent. Controls how nonlinearly pressure scales with density. Default is 7.0.

  • mu (float, optional) – The viscosity of the liquid. Default is 0.005.

  • gamma (float, optional) – The surface tension of the liquid. Default is 0.01.

  • sampler (str, optional) – Particle sampler. Defaults to ‘regular’ for numerical stability with SPH.
