How to turn on corner data in OptiStruct

Hi,

I would like to make and look at contour plots using corner data rather than assign. Despite spending hours looking into this, I can't figure out how to do it (I see a box in OptiView saying 'Use Corner Data' but it is grayed out and I can't click it).

I see that it seems to have something to do with a CSTRESS card, but while I think I can create that card and run the model, it doesn't take effect apparently. Is there something I have to do to link that card to the solver?

Obviously, I'm missing some basic step, so please answer as if I'm five years old.

(If it matters, I'm looking at the 2021.1 version, but I also have access to 2024.

thanks

    to activate 'corner data' you need to request it, under location, before running the model.

    For Stress, in example, it would be like this.

    Thank you very much. This did the trick!

    (I think I had tried this before, but the card data inadvertently cleared when I shut the subwindow maybe? )
