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
factor_radius

Interaction radius is a factor of 4 * particle size

Type:boolean, default False
factor_repulsion

Repulsion is a factor of stiffness

Type:boolean, default False
factor_rest_length

Spring rest length is a factor of 2 * particle size

Type:boolean, default False
factor_stiff_viscosity

Stiff viscosity is a factor of normal viscosity

Type:boolean, default False
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_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
