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
