In many cases, values between 1.0 and 50.0 produce good results, but there is no limit. To get a more turbulent and water-like fluid, increase this factor, but try to avoid very high values (unless necessary), because they can completely distort the fluid. You can enter any positive value ≥ 0. The substeps settings in RealFlow | Cinema 4D's → " Solver" tab influence how this parameter acts on the fluid. 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.

"Viscoelastic" is the choice of materials such as rubber, caoutchouc, silicone, or "memory foam"."Viscous" fluids are suited for substances like caramel, yogurt, oil, or lava."Granular" is suitable for substances like sand or snow."Liquid - PBD" is a very fast fluid type (faster than “Liquid - SPH”)."Liquid - SPH" is a very accurate fluid solver.These particles cannot react with each other and do not have the characteristic fluid properties, but they are simulated very fast. "Dumb” particles are often used for spray or foam.All types, except "Dumb", are GPU-accelerated: There are six different types of fluids and materials.
