For torsional vibration, the motion of each finite element station is described by a rotational displacement about the spinning axis. The systems can be continuous, discrete, or the combination of continuous and discrete. The analyses for torsional vibration are:

Damped and Undamped Natural Frequencies and Modes Calculation
Steady State Forced Response Analysis
Startup Transient Analysis, Synchronous or Induction Motors 
Short Circuit Transient Analysis

For axial vibration, the motion of each finite element station is described by a translational displacement along the spinning axis. The systems can be continuous, discrete, or the combination of continuous and discrete. The analyses for axial vibration are:

Damped and Undamped Natural Frequencies and Modes Calculation
Steady State Forced Response Analysis

For torsional and axial vibration, the modal damping can be specified if the direct damping is not readily available.
