Please tell me how to minimize mass with responses mass and stress (no constraints and bounds are given, only max. von mises stress is known).
Thanks in advance.
Hi Sid98,
Since you know the max stress value, you can use that value as a constraint (use upperbound to constraint stress) and define your Objective as Minimize Mass.
For more information please refer our Optimization-Guide. Follow the below link.

Thank you
So do I have to create only one response i.e. static stress?
You need to create two responses. One to minimize mass and one to constrain stress.
Hello,
Optimization is new to me and while solving an error is displayed as mentioned OPTIMIZATION HAS CONVERGED. INFEASIBLE DESIGN (AT LEAST ONE CONSTRAINT VIOLATED).
please give some solution for it.
Hi Aditya Rai,
May i know what kind of optimization you are performing? and can you give us more details about it (Objective, constraints, responses)
