  In modal analysis, what is the respect of mode shapes such as torsion and bending.As we know by default, modal analysis gives 6 natural frequencies and I just want to know is there any ordinary.

  ANSYS Modal defaults to requesting 6 modes, but a structure has a huge (infinite) number of modes as long as there are a sufficient number of nodes in the model.
  
  You can request more modes under the Analysis Settings. For a simple structure, very high modes are not very useful.
