topology optimization with multiple load cases

Recommended Posts


Dear all,


I am running a topology optimization, but I want to consider multiple load cases at once and not each one separately.

Is that possible? How can I insert all the load cases (five) and only solve one optimization considering all of them?


Thank you in advance

Thank you!!


So I create the response "weighted compliance" and, in my case of 5 load cases of equivalent importance, I set each weighting factor to 0.2, correct?


And then as usual in the objective I set minimize the weighted compliance, correct?


Thank you!

See the equation below for WC, where W is the weight factor. 


If your weight factor is 0.2, the compliance considered for load case1 for example will be 0.2 times of actual compliance.
