How to insert Minimum Compliance or Element Strain Energy as objective function in HyperStudy

Hello, 

I am trying to conduct multi-objective optimization by using HyperStudy, 

After organizing .TPL file and selecting solver as Optistruct, I would like to express compliance as a define output response. 

However, when I drag .out file, it shows me only mass, volume etc.

When I drag .h3d file, it gives me stresses, displacements etc. 

I can not find complaince or element strain energy,

What should I do ? For example, while making outout request from Hypermesh, should I request another global output, 

Thanks for your responses

    Hello Bugra,

     

    Did your OptiStruct job runs successfully. Below is a screenshot of the data I can read from an OptiStruct out file:

    Also, the element strain energy should be available in the h3d, as soon as you pick a modal analysis loadcase.

     

    Does that help,

     

    Best Regards,

    Michael

    Hello Micheal,

    Thanks For Help, 

    I don't have these options, I will attach picture below. What could be the reason ? I can find mass and volume only under component section ? I see you can find them under TYPE tab.

    I think it worked successfully because I can catch see mass, volume, compliance values and didn't encounter any errors in .out file.

    Hello bugra,

     

    what kind of analysis are you running? data such as compliance should be extracted correctly for linear analysis loadcases. To my knowledge linear analysis and modal analysis are supported.

    BTW, if you fail to recover them with the HyperStudy reader, you can still use the file Parser option.

     

    Does that help?

    Best Regards,

    Michael

    Hello Micheal, 

    Actually, I can Share .FEM file. 

    Normally, I conduct Linear Static Analysis

    I am not sure whether I requested suitable outputs in the FEM file

    By the way, do you mean HyperStudy Text Extraction by saying the file Parser Option

    Thanks
