Surface tensionĪ fluid's tendency to contract and create drops and tendrils is increased with higher settings. “External Pressure" tries to limit a fluid’s expansion tendency and can be compared to atmospheric pressure. Particles tend to "stick" together with higher values. This parameter accepts any positive value ≥ 0. This parameter accepts any positive value ≥ 0. “Internal Pressure” simulates the forces between nearby particles and pushes them apart - this makes the fluid fill a greater volume. The density of water is 1,000 kg/m 3. Avoid very small values close to 0, because they can lead to instabilities. This way you are able to simulate substances like oil and water. “Density” does not change the fluid's behaviour, but it is possible to mix fluids from different domains. This parameter is defined as mass per volume unit and is different for each substance. The parameter accepts any positive value.With “Resolution” set to 1.0, a volume of 1 m x 1 m x 1 m contains exactly 1,000 particles.

“Resolution” mainly depends on scene scale and emitter scale, but it also affects the material's mass and therefore depends on “Density”, too: With this setting you can change the amount of particles. For a complete list of possible interactions please visit → this page.
#REALFLOW SNOW HOW TO#
To learn more about how to link RealFlow scene elements and make them interact take a look at the → " Links" page with examples.All fluid, rigid, and elastic containers inside the drag-and-drop field will be affected by the fluid. If there is only one container in the scene it will be linked automatically, otherwise the connection has to be established manually.

for the creation of foam or water-and-oil simulations: RealFlow | Cinema 4D supports interactions between different fluid, rigid, and elastic containers, e.g. Quick access to the "Solver" settings comes in handy when you work with Dyverso materials (granular, viscous, viscoelastic, rigid, elastic).For descriptions of these parameters follow the links. Furthermore you have direct access to the selected "Scene" tree's → " Solver", → " Cache", and → " Display" tabs.To link the "Fluid" node to a different scene tree dragging the appropriate "Scene" node to this field.In RealFlow | Cinema 4D it is possible to use multiple "Scene" trees in the same project: This is the place where the type of fluid/material is defined together with its properties.
