(1) The timestep increment determines how often the program will print positions, velocities, dynamic cable properties, etc., to the output *.POS and *.DCP files. For example, if the timestep increment was five then the printout would contain information on each structure/cable at timesteps 1,6,11,16, etc.

This facility can be used to limit the number of position/velocity output within the given period of time, which is particularly useful in creating an animation (sequence file) without having to have one picture for each time step.
