class genesis.engine.materials.SPH.liquid.Liquid(rho=1000.0, stiffness=50000.0, exponent=7.0, mu=0.005, gamma=0.01, sampler=None)[source]#

Bases: Base

The liquid material class for SPH.

Parameters:

  • rho (float, optional) – The density (kg/m^3) the material tends to maintain in equilibrium (i.e., the “rest” or undeformed state). Default is 1000.

  • stiffness (float, optional) – State stiffness (N/m^2). A material constant controlling how pressure increases with compression. Default is 50000.0.

  • exponent (float, optional) – State exponent. Controls how nonlinearly pressure scales with density. Larger values mean stiffer response to compression. Default is 7.0.

  • mu (float, optional) – The viscosity of the liquid. A measure of the internal friction of the fluid or material. Default is 0.005

  • gamma (float, optional) – The surface tension of the liquid. Controls how strongly the material “clumps” together at boundaries. Default is 0.01

  • sampler (str, optional) – Particle sampler (‘pbs’, ‘regular’, ‘random’). Note that ‘pbs’ is only supported on Linux for now. Defaults to ‘pbs’ on supported platforms, ‘random’ otherwise.
