Thanks for your reply and your valuable time.

I would just like to clarify......I extracted 55 mode shapes only and in 55 modes the error has crossed 50% from the theoritical. So, according to the 12 elements for a sinusoid....upto mode 166 there should be no error. Please comment whether my conclusion is right or wrong.

 

I would like to ask which mass matrix is accurate:consistent or lumped?
