Looking for presets

Two years ago I wrote an article talking about Presets for RF4. This article is off-line now. Anyway that article was based on RF4 but due to some changes in RF5 the performances are different now and more accuracy. You can see some of the videos I did in the RF YouTube channel (Prefix “Preset”).

I would be very glad to reproduce that article here but I have not access to it by now, for that reason I was making several sims to compare for my own. (Videos are HD, it is recommended see ing the videos at full screen. The other parameters not evaluated are set by default)

These are the results.

Density: 250, 1.000, 3.000, 1.0000

The Densities does not use to affect the motion of the fluid,  you can only see the difference using two different fluids with different densities or involving dynamic bodies in the simulation, in the next example the object has a mass of 4375 units, approximately same density as water (1000 units) the fluid has different densities.

Density: 100, 1.000, 10.000, 50.000

The different Viscosities are more evident in the next examples.

Viscosity: 3, 5,  25, 100

In the case of the Surface Tension you can see more particles are grouped when higher values are used in the surface tension parameter.

Surface Tension: 2, 10, 25, 100

But the best way to see the effect is using less particles.

Surface Tension: 0, 1, 10, 100, 1.000, 10.000, 100.000
