In optistruct profile,when i specify the stress result at corner and center option for shell elements ,the two types of result seem to be the same as that of the center location?But the same model'result in nastran profile are different(the stress location result option is effective)

Does that mean the location setting in optistruct is useless?

i wish to attach the two types of result in contour plot image,but it seem to be unavailable in the post page

    Optistruct cannot use corner stresses to use as a responce for optimisation. It can only use centroidial.

    I have spoken to the person responsible for this in Altair. Hopefully it will be fixed.
