Selected subcase is not compatible with the type of response

Hi,

I´m writing my bachelor thesis at the moment and got some trouble while setting up the optimization problem. I want to add a static displacement constraint, but hypermesh displays the error message 'Selected subcase (XYZ) is not compatible with the type of response' when I try to set an upper bound using the dcontraints panel for the static displacement response I created before.

The Model got 4 Load Steps of the type 'Linear Static'. It is meshed with Hexa-Elements. Furthermore it uses bolt pretension, CBEAM and RBE2 Elements. For contactmodeling I only use FREEZE and SLIDE.

Are there any incompabilities with repect to my FEM Setup or has anyone an idea why this error message is displayed? I have never had such a problem before.

If I only run the analysis, there are no problems and the model behaves as expected.
