How to setup Optistruct static analysis output control cards to export results for just a set of elements

I have setup an Optistruct analysis to export displacement, strain energy, and stress results to a punch file using the PARAM, EXTOUT, DMIGPCH command, as well as the GLOBAL_OUTPUT_REQUEST DISPLACEMENT(PUNCH), ESE(PUNCH), and STRESS(PUNCH) commands. I would like to now export these same results for just a user defined set of elements using the Hypermesh GUI. Could someone explain how to do this?

    Use SID and refer the set in Global output request,

    EDIT: SOLVED. Thanks!

     

    I don't see any option to refer to the SID inside of the DISPLCAMENT/ESE/STRESS settings. Do I select a 4th flag and define the SID inside of that?

    Hi @baker1213

     

    Under options change ALL to SID

    Going to give this a bit of an old bump but it does relate. I'm used to using ABAQUS and know how to do it there, but am still learning the intricacies with Optistruct. I'm essentially looking to output displacements of nodesets to a text file for convenience. I have defined my nodesets as follows:

    However, nothing shows up when I try to select the nodesets:image

    I've tried adding a card image and playing around with the various set settings to no avail. Does anyone know what I'm doing wrong here? I'd greatly appreciate the help. Thanks!
