Composite failure constraints

Hi, I'm optimizing a composite model and I want to constrain the failure.
I created the composite failure response and then created the constraint applied to all of my loadcases with an upper bound of 1.

I don't see CFAIL as an output option in control cards so added CFAIL(ALL) = ALL to the .fem file or in CASE_UNSUPPORTED_CARDS  in control cards.

Observing the results in hyperview show that only ply failure is observed by the optimization and that bond failure is not.

Is there a different form of  failure constraint that would allow the optimization to adhere to bond failure as a constraint?

 

Thanks,
