Hi guys! I’m trying to use optistruct on Hypermesh to carry out topology optimisation. I keep getting this error - error #551. Can anyone help out please?

“DTPL and DSIZE cards require DESOBJ data when advanced options are requested or when PBUSH properties are used.”

    Hi,

     

    you need to share more information about your 'responses', 'constraints' and objective in order to get help, please.

    apparentyl you need to create an 'ojective reference' and then call this one as your objective, by usng minmax or maxmin.

    But with no other information, it is hard to tell.
