    Thanks for your reply.

     

    I have one more question.

     

    In your attachment it is mentioned as Residual vector calculates the displacement vectors of a static analysis based on dynamic loading. In FRA how static analysis is calculated and how it improves the results.

     

    Thanks in advance.
