< BLOCKQUOTE > 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 < I > density< / I >
and < I > viscosity< / I > . 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 < CODE > setOverrideRadius()< / CODE > method.< / BLOCKQUOTE >
