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 its rest length

Type

float in [0, 1], default 0.0
