Detailed Description

An operator that simulates the friction of a fluid. By using this operator you can let the particles move in a fluid of a given density and viscosity. There are two functions to quickly setup the parameters for pure water and air. You can decide whether to compute the forces using the particle's physical radius or another value, by calling the setOverrideRadius() method.
