base class — `bpy_struct`

class `bpy.types.``SPHFluidSettings`(bpy_struct)

  Settings for particle fluids physics

  `buoyancy`

    Artificial buoyancy force in negative gravity direction based on pressure differences inside the fluid

    Type: | float in [0, 10], default 0.0

  `fluid_radius`

    Fluid interaction radius

    Type: | float in [0, 20], default 0.0

  `linear_viscosity`

    Linear viscosity

    Type: | float in [0, 100], default 0.0

  `plasticity`

    How much the spring rest length can change after the elastic limit is crossed

    Type: | float in [0, 100], default 0.0

  `repulsion`

    How strongly the fluid tries to keep from clustering (factor of stiffness)

    Type: | float in [0, 100], default 0.0

  `rest_density`

    Fluid rest density

    Type: | float in [0, 10000], default 0.0

  `rest_length`

    Spring rest length (factor of particle radius)

    Type: | float in [0, 2], default 0.0

  `solver`

    The code used to calculate internal forces on particles

    - `DDR` Double-Density, An artistic solver with strong surface tension effects (original).
    - `CLASSICAL` Classical, A more physically-accurate solver.

    Type: | enum in [‘DDR’, ‘CLASSICAL’], default ‘DDR’

  `spring_force`

    Spring force

    Type: | float in [0, 100], default 0.0

  `spring_frames`

    Create springs for this number of frames since particles birth (0 is always)

    Type: | int in [0, 100], default 0

  `stiff_viscosity`

    Creates viscosity for expanding fluid

    Type: | float in [0, 100], default 0.0

  `stiffness`

    How incompressible the fluid is (speed of sound)

    Type: | float in [0, 1000], default 0.0

  `use_factor_density`

    Density is calculated as a factor of default density (depends on particle size)

    Type: | boolean, default False

  `use_factor_radius`

    Interaction radius is a factor of 4 * particle size

    Type: | boolean, default False

  `use_factor_repulsion`

    Repulsion is a factor of stiffness

    Type: | boolean, default False

  `use_factor_rest_length`

    Spring rest length is a factor of 2 * particle size

    Type: | boolean, default False

  `use_factor_stiff_viscosity`

    Stiff viscosity is a factor of normal viscosity

    Type: | boolean, default False

  `use_initial_rest_length`

    Use the initial length as spring rest length instead of 2 * particle size

    Type: | boolean, default False

  `use_viscoelastic_springs`

    Use viscoelastic springs instead of Hooke’s springs

    Type: | boolean, default False

  `yield_ratio`

    How much the spring has to be stretched/compressed in order to change it’s rest length

    Type: | float in [0, 1], default 0.0

  classmethod `bl_rna_get_subclass`(id, default=None)

    Parameters: | id (string) – The RNA type identifier.
    Returns: | The RNA type or default when not found.
    Return type: | `bpy.types.Struct` subclass

  classmethod `bl_rna_get_subclass_py`(id, default=None)

    Parameters: | id (string) – The RNA type identifier.
    Returns: | The class or default when not found.
    Return type: | type
