class genesis.engine.materials.MPM.liquid.Liquid(*, use_visual_raycasting: bool = False, E: float = 1000000.0, nu: float = 0.2, rho: float = 1000.0, lam: float | None = None, mu: float | None = None, sampler: str = 'pbs', update_F_S_Jp: Any = None, update_stress: Any = None, needs_svd: bool = True, idx: int | None = None, viscous: bool = False)[source]#

Bases: Base

The liquid material class for MPM.

Parameters:

  • E (float, optional) – Young’s modulus. Default is 1e6.

  • nu (float, optional) – Poisson ratio. Default is 0.2.

  • rho (float, optional) – Density (kg/m³). Default is 1000.

  • viscous (bool, optional) – Whether the liquid is viscous. Simply sets mu to zero when non-viscous. Default is False.

viscous: bool#
model_post_init(context: Any) → None[source]#

Override this method to perform additional initialization after __init__ and model_construct. This is useful if you want to do some validation that requires the entire model to be initialized.

model_config: ClassVar[ConfigDict] = {'extra': 'forbid', 'strict': True, 'validate_default': True}#

Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].
