hello,
i'm doing a size optimization in order to match the drequencies targets for the first 10 modes.
so i defined my design variable wich is the PBUSH stifness k1..k6
and as and objective is the MIn using DSYSID (iwth all the 10 first frequancies and the targets) but some how i don't have the right results thats i want
i have in my model
DESVAR refered to stifness of PBUSH
DVPREL1
DRESP1
MIN WITH a DSYSID
everythings is well defined i don't if there something else to add to my optimization to work
