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 (in [0, 10], default 0.0)

Type:

float

fluid_radius

Fluid interaction radius (in [0, 20], default 0.0)

Type:

float

linear_viscosity

Linear viscosity (in [0, 100], default 0.0)

Type:

float

plasticity

How much the spring rest length can change after the elastic limit is crossed (in [0, 100], default 0.0)

Type:

float

repulsion

How strongly the fluid tries to keep from clustering (factor of stiffness) (in [0, 100], default 0.0)

Type:

float

rest_density

Fluid rest density (in [0, 10000], default 0.0)

Type:

float

rest_length

Spring rest length (factor of particle radius) (in [0, 2], default 0.0)

Type:

float

solver

The code used to calculate internal forces on particles (default 'DDR')

  • DDR Double-Density – An artistic solver with strong surface tension effects (original).

  • CLASSICAL Classical – A more physically-accurate solver.

Type:

Literal[‘DDR’, ‘CLASSICAL’]

spring_force

Spring force (in [0, 100], default 0.0)

Type:

float

spring_frames

Create springs for this number of frames since particles birth (0 is always) (in [0, 100], default 0)

Type:

int

stiff_viscosity

Creates viscosity for expanding fluid (in [0, 100], default 0.0)

Type:

float

stiffness

How incompressible the fluid is (speed of sound) (in [0, 1000], default 0.0)

Type:

float

use_factor_density

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

Type:

bool

use_factor_radius

Interaction radius is a factor of 4 * particle size (default False)

Type:

bool

use_factor_repulsion

Repulsion is a factor of stiffness (default False)

Type:

bool

use_factor_rest_length

Spring rest length is a factor of 2 * particle size (default False)

Type:

bool

use_factor_stiff_viscosity

Stiff viscosity is a factor of normal viscosity (default False)

Type:

bool

use_initial_rest_length

Use the initial length as spring rest length instead of 2 * particle size (default False)

Type:

bool

use_viscoelastic_springs

Use viscoelastic springs instead of Hooke’s springs (default False)

Type:

bool

yield_ratio

How much the spring has to be stretched/compressed in order to change its rest length (in [0, 1], default 0.0)

Type:

float
