Fluid 2D Affector
Applies a fluid simulation to a field.
Fluid 2D Affector
Method #
This node applies a fluid solver to the velocities of the field system, creating eddies and swirls like a gas or liquid. This solver uses the grid-based Navier Stokes method, maintaining incompressible pressures using multiple iterations of a process over the field’s voxel grid, and can have a sizeable performance impact with high-resolution fields.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details Simulation Speed Controls the speed of the fluid simulation.
Vorticity Confinement Scale Controls the amount of vorticity confinement, which increases the number of small swirls in the fluid system.
Diffusion Amount How much the field colours are diffused to neighbouring voxels.
Velocity Dampening How much velocities are dampened and averaged across the field system.
Solver Iterations How many times the fluid system solver is run. Higher values improve accuracy, but lower performance.
