Hello all,

I am currently performing modal analysis of Hybrid III dummy model.  I am fixing the buttock and feet components as a fixed support. I am unable to observe the proper mode shape behavior of human body and receiving initial frequencies very less i.e. close to zero. I intend to evaluate the resonant modes in human body and natural frequency computation. I am using non-linear actual material properties in default Hybrid III dummy model and other constraints and contact in predefined model.

Can anyone have idea how to configure Hybrid III dummy model to perform natural frequency and mode shape calculation? How to analyze and interpret mode shape behaviors in Hybrid III dummy model in different directions?

I am using following control cards.

*BOUNDARY_SPC

*CONTROL IMPLICIT EIGENVALUE *CONTROL IMPLICIT GENERAL *CONTROL IMPLICIT SOLUTION

Any assistance in this regard would be highly appreciated.

Regards,

Vaibhav.
