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 110.
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.
