Houdini 19.0 Nodes Dynamics nodes

Particle Fluid Density CL dynamics node

Solves a Smoothed Particle Hydrodynamics (SPH) density constraint for fluid particles using OpenCL.

Since 19.0

The Particle Fluid Density CL DOP solves the SPH density constraint for fluid particles by updating the particle positions using OpenCL. This DOP requires several point attributes present to work correctly:

Type

Name

Description

float

pscale

The size of the particle.

integer

phase

Any value greater than zero indicates that a particle should be treated as fluid.

float

mass

The mass of the particle.

integer array

neighbors

An array of any neighbor particles within the Kernel Width.

The Vellum Configure Grain SOP can be used to create particles in the proper initial configuration when set to Fluid mode.

Parameters

Geometry

The name of the data holding the geometry upon which to operate.

Kernel Width

The size of the neighborhood around each particle to use when estimating the SPH density. This value is a scale on the particles' pscale attribute.

Volume Scale

A scale on the amount of volume of the fluid each particle represents.
