  How do I perform stability analysis on a shaft ? (Ansys workbench)
  
  Is stability analysis just getting a time decay graph?
  
  If someone can explain what exactly is Stability analysis ?
  
  Thanks

  In other posts, you were given links to the Rotodynamic Analysis Guide. Read section 6.7.2

  6.7.2. Check the Stability and Whirl of Each Mode
  
  Forward (FW), and backward (BW) whirls, and unstable frequencies are identified in the Campbell diagram analysis. These characteristics appear in the Campbell diagram graphic legend generated by the PLCAMP command. Forward and backward whirls are printed out in the table generated by the PRCAMP command, as shown below.
