FEMWATER particle tracking refers to the algorithm used by FEMWATER to do advective transport. In GMS versions 6.5 and earlier there was another type of particle tracking available which was similar to MODPATH but for FEMWATER flow solutions. That functionality is documented on the FEMWATER Particle Sets page.
Page 32 of the FEMWATER manual describes the particle tracking used in advective transport. However the algorithm described is not actually used in the code. Instead a simpler adaptive timestepping algorithm is used. The parameter NXW is used as a "time step divisor" - backtracking begins by assuming a subtimestep, and every time backtracking fails, this subtimestep is divided by 2. NXW is used as an "Initial number of steps per time step" and the other parameters on the PT1 card are ignored.
