Modal analysis with rigid elements

      Hi,


      I would like to know if it is possible to perform a modal analysis with an assembly composed of rigid elements? My first results show a very high frequency about 10^5 hz... 


      thank you for your answer,


      Best,

      Hi, 


      Do you mean you want to study the mechanism of a rigid body system? Like several rigid bodies connected by joints?

      Hi Wenlong,


      thanks for your help.


      I have 3 bodies: One rigid body which is connected to another rigid body by a flexible body. 


      I would like to get the resonance frequency of the whole system, it is possible ?


      Regards,

      Hi,


      Yes, mixing rigid bodies and flexible bodies is possible in modal analysis. 


      Regards,
