Int Pressure
Internal pressure goes from 0 to 1, and simulates the forces between nearby particles and pushes them apart - this makes the fluid fill a greater volume.
...
Ext Pressure Scale
This parameter goes from 0 to 1, and tries to limit a fluid’s expansion tendency and can be compared comparable to atmospheric pressure. Particles Particles tend to "stick" together with higher values. The substeps and iterations settings in the "Scene" node's → "Solver" tab influence how this parameter acts on the fluid.
...
Higher settings increase a fluid's tendency to contract and form string-like structures. As a side-effect, the fluid's borders become thicker. "Tensile strength" accepts any positive value, but should not be greater than value between 0 an 1.
Viscosity
This parameter lets you create substances like cream, chocolate, oil, honey, or tooth paste:
...
"Cohesion" is a force of attraction between nearby particles. With particle streams you will get a look similar to toothpaste or thick paint coming out of a tube. Any value ≥ between 0 ans 1 is accepted. The substeps and iterations settings in RealFlow's → "Simulation Options" influence how this parameter acts on the particles.
...
Damping smoothens the relative velocities between nearby particles. A small amount of damping helps to stabilize a simulation, while higher values introduce (more) viscosity to the material. The range goes from 0 to 10.
Max particles
Please enter a value to stop emission at a certain amount of particles. "Max particles" is based on the total amount of emitted particles. Let's say you have entered "50,000". If there are currently 1,000 particles in your scene, but you have already deleted 49,000 particles RealFlow will stop the emission.
