Comments

  1. /ADYREL is based on /DYREL but the period to be damped is automatically calculated and varies during the simulation.
  2. The line with Tstart and Tstop is optional. If the start and stop times are not included the adaptive dynamic relaxation is active until the end time defined by /RUN.
