Sensitivity analysis with multiple functions of interest

Please login with a confirmed email address before reporting spam

Hello,

I am trying to carry out a sensitivity analysis where multiple functions of interest are considered but not summed. For instance, in the context of solid mechanics, I would like to evaluate the compliance sensitivity with respect to a control variable 1 and I would like to also evaluate the maximum stress sensitivity with respect to control variable 1.

At the moment, to do so, I create 2 studies with a sensitivity component in each of them. However, it means I have to solve the solid mechanics problem twice which is inefficient. Ideally, I would like to solve the mechanical problem only once and to carry out as many sensitivity analysis as needed. It seems that I cannot have two sensitivity components in one study and that the only option in the sensitivity component is to sum the objectives.

Any feedback would be greatly appreciated.

Thank you, Alex
