Hey, 

I am running a free-size optimization using static displacement as a response. When i run the optimiziation, this error appears:

 

*** ERROR # 557 ***
DRESP1 2 is not referenced from within a static or an MBD SUBCASE.
This type of response must be specified from within a static or an MBD
SUBCASE.
This error occurs in DESOBJ 2.

 

How does one specify a response from within a subcase?

Thanks

    Where are you using this response? In constraints or objective wherever you are calling this response there must be a field for loadstep. You need to refer what loadstep are you calling the response from.
