* ERROR # 583 *

Hello,

checking the model before running the analysis there was a fatal error:

'*** ERROR # 583 *** Missing objective, DESGLB and DESSUB data must be used together with an objective function defined by DESOBJ, MINMAX, or MAXMIN.'

In this forum, I've found this but I don't understand how to solve the problem.

Someone can help me, please?

Regards

Hello Rahul R,

thanks for your answer, the problem is design objective.

Now another problem born shown in the image, but there is no objective folder.

Where am I doing wrong?

Thank you

Have you already defined Volume as Design constraint? If so, then it should not work. I see you have only one optimization response.
