System identification with Hyperstudy

Hi all,

for my optistruct analysis deck (see attachment), I would like to do a system identification.

What I would have to do is to modify this analysis deck into an analysis deck for Hyperstudy, where I can calculate the transfer function, compare the transfer function to a measured transfer function and optimize the CBUSH in order to align the two transfer functions.

Attached find the complete optistruct model (analysis deck is named os_lds_block.fem) and a png-file of the calculated model with an explanation of it's super elements (os_lds_block.png). 

Does anyone know how to make the necessary changes in the analysis deck, to perform a system identification with Hyperstudy?

Kind regards
