Dear ResearchGate Community,

I am currently working on Topology Optimization for a composite CS-23 aircraft fuselage. I have different load cases that I want to apply separately to the model to obtain individual topology designs. Subsequently, I aim to assign weights to the load cases based on the determined compliance (maximum strain energy in Abaqus, I presume). Ultimately, all load cases should be applied simultaneously, considering the individual weight factors. I am aware that the feature of "weighted compliance" exists in Altair OptiStruct. However, I am uncertain how to achieve this in Abaqus Tosca. So far, I have only found the option to apply different load cases one after another, without incorporating weight factors.

Perhaps some of you are familiar with how to accomplish this.

Thank you in advance.
